Understanding the interplay between bulk composition and metamorphic grade underpins our interpretations of metamorphism in orogenic belts. The focus of this study is the regional garnet–staurolite–kyanite–sillimanite metamorphic sequence of the Whetstone Lake area, southeastern Ontario. In the kyanite and lower sillimanite zones of this area, there is exceptional diversity in metapelitic mineral assemblages that cannot be accounted for by differences in metamorphic grade. We present a data set of petrographic observations, phase proportions, whole-rock geochemical compositions, and mineral compositions, from thirty-two samples that encapsulate the range of assemblages found in these zones. Differences in bulk composition are the primary control on mineral assemblage development. Whole-rock XMg = molar MgO/(MgO + FeO) and |${\textrm{X}}_{\textrm{Fe}^{3+}}=\kern0.5em \textrm{molar}\ 2\times{\textrm{Fe}}_2{\textrm{O}}_3/\left(2\times{\textrm{Fe}}_2{\textrm{O}}_3+\textrm{FeO}\right)$| exert the greatest control on the observed mineral assemblages, whilst variation in MnO, K2O, and Al2O3 have a secondary influence. We use a set of quality factors (Duesterhoeft & Lanari, 2020) to test the ability of thermodynamic models to reproduce the observed mineral assemblages, modal abundances, and mineral compositions in the diverse bulk compositions at Whetstone Lake. Eight samples were selected for phase equilibrium modelling, for which two bulk compositions were calculated for each sample: (1) a whole-rock bulk composition based on an X-ray fluorescence analysis and (2) a carefully considered local bulk composition based on combining mineral proportions with representative mineral compositions, as obtained from a single thin section. Our modelling uses thermodynamic data set 6.2 (Holland & Powell, 2011) and the solution models of White et al. (2014a , 2014b) that incorporate several Fe3+ end members needed to model the natural data. Modelling in both types of bulk composition broadly predicted mineral assemblages that match those observed. In addition, predicted mineral assemblage fields overlap within uncertainty between 620°C and 675°C and between 6.5 and 7.5 kbar, consistent with the limited range of grade represented by the natural rocks. Predicted modal abundances better match those observed when phase diagrams are constructed using local bulk compositions compared to whole-rock bulk compositions. Despite the acceptable agreement between predicted and observed mineral assemblages, consistent discrepancies are found between predicted and observed mineral compositions. These include overestimation of |${\textrm{X}}_{\textrm{Mg}}^{\ast }$| in garnet, staurolite, and cordierite, overestimation of Ti in staurolite and biotite, underestimation of Si in biotite, and overestimation of Al and underestimation of Fe3+, Fe2+, and Mg in muscovite. The Whetstone Lake suite of this study will be useful to test the predictive capability of future thermodynamic models. [ABSTRACT FROM AUTHOR]

Taking the Zhongqiu 1 Gas Field in the Tarim Basin as an example, the heterogeneity of large-scale mono-block gas fields and their primary controlling factors have been analyzed. Based on drilling core data, well log data, scanning electron microscopy, thin-section analysis, and mercury injection experiments, combining sedimentological interpretation, research on the reservoir characteristics and variability was carried out. The results showed that: (1) The lithologic characteristics showed obvious variations among wells in the Zhongqiu 1 gas field. Specifically, the main lithology developed in the Zhongqiu 1 well is feldspar lithic sandstone, while the remaining wells predominantly consist of lithic feldspar sandstone. These differences in rock composition maturity reveal that a higher proportion of stable mineral components leads to poorer reservoir properties; (2) the main factors controlling oil and gas productivity include the variations in petrology, mineralogy, and diagenetic process characteristics. The high content of unstable mineral components and constructive diagenesis could increase reservoir porosity together. (3) Sedimentary facies of the Bashijiqike Formation in the Zhongqiu 1 Gas Field played a dominant role in the reservoir distribution. The division of sedimentary facies zones reflects variations in material composition and grain size, serving as the main material basis for reservoirs. Differences in mineral composition reflect the sedimentary environment of the reservoir. Additionally, mineral composition indicates the relationship between diagenetic processes and reservoir evolution. The high feldspar content in well ZQ1 corresponded to relatively favorable reservoir properties. The dominant feldspar type was plagioclase, suggesting that early-stage chemical weathering had undergone significant alteration. The above conclusions provided a microscopic perspective to explain the differences in oil and gas production capacity of large delta-front gas fields, serving as a geological basis for the exploration and exploitation of similar fields.

This article is the result of a scrupulous investigation of a conceptual issue of the methodology for studying the verbal text of a rock composition as an element of a synthetic text. Based on the well-established idea in the research community about the need to create / use interdisciplinary methods to analyze the verbal subtext of a rock composition, the authors of this study have tried to include the category of image in the methodology of the philological analysis of the verbal component. As a result of the study, the authors conclude that the required structural elements of the verbal component of a rock composition, which distinguish it from both non-synthetic and other synthetic texts, are the phonic level and the subject organization. Considering the subject organization as the central category of not only the verbal subtext of a rock composition, but also of rock and roll discourse in general, the authors introduce and use the term “image character” in the analysis of E. Letov’s work, which allows them to move away from the traditional classification of lyrical subjects and to reveal the links between the lyrical subject of lyrics and the hero of the biographical myth created by the rock poet. The second significant achievement reported in this article is the identification and perception of the phonic level of the verbal text of a rock composition as a marker that distinguishes its text of a traditional, “printed” poem. It is not by chance that all observations made by the authors regarding the phonic organization of lyrics have turned out to be valuable. It was important for the authors not so much as to show the difference between lyrics and a poem (although it was important too), but rather to demonstrate the adherence to principles even in the formal structures of a performing supertext.

The presence of asphaltenes and polar compounds in a crude oil plays a major role in dictating the type of wettability it displays with oil reservoir rocks. The main objective of this study was to investigate the effect of the asphaltenes structure and other polar compounds in altering rock wettability. Five, natural crude oil samples were used with varying asphaltene (6.4 to 11.6), total nitrogen (0.029 to 0.097) and sulfur (2.259 to 4.234) contents, all in mass%. Crude oil characterization showed the asphaltene samples to consist of condensed hydrocarbon and sulfur aromatic molecules with one or two sulfur atoms per molecule. The weight-average numbers of fused aromatic rings for hydrocarbon molecules were 6 to 7 and for sulfur-containing molecules was an average of 8 aromatic rings, where the aromatic systems were substituted with short alkyl chains of less than 20 carbon atoms. Based on mass spectral evidence, the average empirical molecular structures of the asphaltenes were constructed and they were all found to be relatively similar. Entrained maltene species with 2 to 5 aromatic rings with longer alkyl chains were also found. Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) was used to characterize each crudes’ asphaltenes fractions. Three rock samples with mineral compositions of 100% dolomite (D100), 100% calcite (C100), and 63% calcite + 37% dolomite (C63D37) were used. Variation of the contact angle with time was measured using brine, as the external phase, and the five crudes on the rock samples. The interfacial tension (IFT) between brine and the five crudes were also measured. Among the five crude types, the three rocks show the strongest wetting tendency when contacted by type V oil. These were 129.2°, 109.2°, and 135.1° for D100, C100 and C63D37, respectively. Interestingly, wettability was not linearly correlated with asphaltene contents for all crude types. Wettability varied with the rock sample, nitrogen and sulfur contents, and crude’s non-asphaltenic composition. As a result, there is no strong evidence suggesting that the content nor the structure of the asphaltenes alone has a large effect on altering rock wettability.

Many cultural heritage sites in Mexico have been built with volcanic tuff rocks from the earliest Central American civilizations to the time of the Spanish conquest and up to the present. Throughout this long period of time, the stones have been subjected to progressive weathering as evidenced by different types of damage phenomenon such as scaling, sanding, crumbling, sugaring and salt efflorescence. This study utilizes a collection of 53 tuffs from different regions in Mexico that show a diverse range of colors, rock compositions and mineralogy, and heterogeneous rock fabrics indicative of their volcanic origin. Comprehensive investigations have been done that include detailed petrographic analyses, cathodoluminescence, clay mineral analyses, and the determination of a wide range of petrophysical properties (e.g., porosity, capillary water uptake, water absorption, sorption, hydric and thermal expansion, and mechanical properties). All analyzed data combined are used for derivation of some general trends concerning the suitability/durability of tuffs applied as natural building stones. [ABSTRACT FROM AUTHOR]

Therefore, this discussion will have more important strategic signilicance for the exploration and exploitation ol lithium resources. [ABSTRACT FROM AUTHOR]

Abstract This paper presents results of an experimental study to characterize the law of mineral change of fallen rock in coal mine groundwater reservoir ant its influence on water quality. The minerals of the underground reservoir of Daliuta Coal Mine is taken as the research object. Simulation experiments were designed and conducted to simulate water–rock action in the laboratory. The mineral composition was analyzed by X-ray diffractometer (XRD), the surface morphology of the mineral was analyzed by scanning electron microscope (SEM), and the specific surface area, total pore volume and average pore diameter of the mineral were measured by fast specific surface/pore analyzer (BET). The experimental results show that the sandstone and mudstone in the groundwater reservoir of Daliuta Coal Mine account for 70% and 30%, respectively. The pore diameter is 15.62–17.55 nm, and pore volume is 0.035 cc/g. Its pore structure is a key factor in the occurrence of water–rock interaction. According to the water–rock simulation experiment, the quartz content before the water–rock action is about 34.28%, the albite is about 21.84%, the feldspar is about 17.48%, and the kaolinite is about 8.00%. After the water–rock action, they are 36.14%, 17.78%, 11.62%, and 16.75%, respectively. The content of albite and orthoclase is reduced while the content of kaolinite is increased, that is, the Na+ content becomes higher, and the Ca2+ and Mg2+ contents become lower. This research builds a good theoretical foundation for revealing the role of water and rock in underground coal reservoirs.

Highlights • Objective method for crustal modeling based on Bayesian inference is developed and applied to Japan arc. • Biases in conventional geochemical methods are investigated and a new bias-free rock composition model is presented. • Geo-neutrino flux from the Japan crust is calculated with fully probabilistic uncertainty estimation. Abstract Geoneutrino observations, first achieved by KamLAND in 2005 and followed by Borexino in 2010, have accumulated statistics and improved sensitivity for more than ten years. The uncertainty of the geoneutrino flux at the surface is now reduced to a level small enough to set useful constraints on U and Th abundances in the Bulk Silicate Earth (BSE). However, in order to make inferences on earth's compositional model, the contributions from the local crust need to be understood within a similar uncertainty. Here we develop a new method to construct a stochastic crustal composition model utilizing Bayesian inference. While the methodology has general applicability, it incorporates all the local uniqueness in its probabilistic framework. Unlike common approaches for this type of problem, our method does not depend on crustal segmentation into upper, (middle) and lower, whose classification and boundaries are not always well defined. We also develop a new modeling method to infer rock composition distributions that conserve mass balance and therefore do not bias the results. Combined with a new vast collection of geochemical data for rock samples in the Japan arc, we apply this method to geoneutrino observation at Kamioka, Japan. Currently a difficulty remains in the handling of correlations in the flux integration; we conservatively assume maximum correlation, which leads to large flux estimation errors of 60–70%. Despite the large errors, this is the first local crustal model for geoneutrino flux prediction with probabilistic error estimation in a reproducible way. [ABSTRACT FROM AUTHOR]

The problem of comparison of the composition of crystalline rocks with the composition of the constituent minerals of these rocks is considered. It is proposed to present the composition of rocks and the compositions of the constituent minerals in the form of a triangle on the plane. The experience of presentation of compositions in phase diagrams was taken as a basis for the construction. Analysis of the crystallochemical characteristics of clinopyroxenes and garnets has shown that three parameters are enough for depicting the compositions of these and other minerals. For this purpose, similar composition components of rocks and their minerals are summarized in molecular proportions and are plotted on the triangle DO-1/2(R 2 O3)-XO 2 , where DO = (MgO + CaO + FeO + MnO + NiO + ...) + 1/4(Na 2 O + Al 2 O 3 ) + 1/4(K 2 O + Al 2 O 3 ), 1/2(R 2 O 3 ) = 1/2(Al 2 O 3 + Fe 2 O 3 + Cr 2 O 3 + ...) - (1/4(Na 2 O + Al 2 O 3 ) + 1/4(K 2 O + Al 2 O 3 )), and XO 2 = SiO 2 + TiO 2 . The compositions of minerals are expressed as the sums of their components: Ol = Fo + Fa + Lar + Neph + ..., Px = Di + En + Wol + Ged + Gip + Jd + Eg + ..., Ga = Pyr + Gross + Alm + Spe + Ski + Knr + Mj + ..., etc. A step-by-step calculation algorithm is proposed, which permits evaluation of the contents of bi- and trivalent iron during probe microanalyses of garnets and pyroxenes. Comparison of the compositions of deep-seated rocks and their minerals shows their good consistency. The proposed schematic projection permits a visual comparison of the compositions of rocks with low contents of carbonates and water, from ultrabasic (e.g., dunites) to acid (e.g., granites) ones.

In the process of CO 2 -EOR and post-EOR, CO 2 injection broke the original physical and chemical balance in reservoirs, and caused the complex CO 2 -brine-rock interactions, meanwhile, it leaded to the variations of rock composition, clay mineral, porosity, pore structure, water salinity, water type and pore fluid. By analyzing the model, core experimental study, field implementation of detection and so on, many scholars studied the CO 2 -brine-rock interactions and the variations of rock composition, porosity and others. The results showed that CO 2 injection would lead to quartz, feldspar, carbonate mineral and clay mineral component dissolution and to the formation of new minerals, which would lead to the decrease of the reservoir porosity. The implementation of ECS time-lapse logging was helpful to predict the variation of rock composition. Neutron and acoustic time-lapse logging were helpful to predict the porosity variation.

Several laboratory studies observed wettability alteration of carbonate rocks towards a more water-wet state through modifying the composition of injected water. The change in carbonate surface charge was reported as the underlying reason behind this wettability alteration and the corresponding incremental oil recovery by engineered water injection (EWI). Although the reported results of carbonate rock sensitivity to injected water ionic strength, pH, salinity, and concentration of potential determining ions (Ca2+, Mg2+, and SO 4 2−), there is still an ambiguity on the way carbonates interact with injected water/ions. This is due to the different mineralogical compositions and electrokinetic properties of carbonates. Therefore, this paper provides more insight into the role of major rock-forming carbonate minerals (calcite and dolomite) in engineered water injection at different water compositions by utilizing surface complexation modeling (SCM). The study utilizes a geochemical simulator to highlight the effect of dolomite surface complexation reactions. After determining the total rock surface charge and surface potential, the disjoining pressure was calculated to estimate the water film thickness and consequently, infer about wettability alteration. The results showed that a successful EWI operation creates three regimes: displacement regime, surface reaction regime, and quasi-equilibrium regime. These regimes can be characterized by the proposed surface complexation technique to calculate/optimize the injection pore volumes needed for each regime, determine the location of EWI effect in the reservoir, and predict the time ranges when EWI will reach to the surface in the form of additional oil recovery. Also, it was found that the surface reaction regime is the most important one where main surface reactions and oil recovery occur. Furthermore, the study utilizes SCM for both calcite and dolomite minerals for the first time highlighting their importance in geochemical reactions of EWI when the rock has dolomite in its composition. Existing SCM considers oil-brine and rock-brine interfaces where only calcite mineral is captured in the rock-brine interface. The latter is based on assuming that the rock composition is pure calcite, which is not necessary the case. The findings of this study confirm that seawater is capable of inducing wettability alteration in carbonates under certain favorable conditions due to adsorption/desorption of the potentially determining ions. • This paper provides novel insight into the role of major rock-forming carbonate minerals (calcite and dolomite) in EWI/LSWI at different water compositions by utilizing the surface complexation reactions. • It is found that in a successful EWI operation, three regimes would be created, i.e. displacement regime, surface reaction regime, and equilibrium regime. • These regimes can be characterized by the proposed technique to calculate/optimize the injection pore volumes needed for each zone. • The developed approach can determine the location of EWI effect in the reservoir, and predict the time ranges when EWI would reach to the surface in the form of additional oil recovery. • This study utilizes SCM for both calcite and dolomite minerals for the first time highlighting their importance in geochemical reactions during EWI when the rock has dolomite as a constituent.

Weathering processes cause important changes in the engineering properties of rocks. In this study, dunites in the Bursa region in western Turkey were investigated and the changes in engineering properties due to weathering were evaluated. The studies were initiated with field observations including measurement of the characteristics of discontinuities such as spacing, aperture, fill material, roughness, and Schmidt hammer rebound value. Subsequently, laboratory studies were conducted in two stages. The first stage comprised mineralogical, petrographic, and chemical analyses. The second stage included physicomechanical tests to determine specific gravity, unit weights, water absorption, effective porosity, uniaxial compressive strength, P-wave velocity, and slake-durability index. According to these evaluations, the changes in engineering properties were determined to be mostly related to serpentinization at every stage of weathering. The most suitable parameters for characterizing the degree of weathering of the studied dunites are loss-on-ignition values, specific gravity, unit weight, water absorption, and effective porosity.

Abstract: Since long time Raman scattering revealed to be a very sensitive and easy technique to deal with the detection of mineral compounds, due to their vibrational fingerprint. However, presence of small inclusions or identification of grains with very small dimensions in rocks may still remain problematic for normal Raman detection apparatus. In this work, we propose to apply the SERS (surface-enhancement Raman scattering) effect to micro-Raman measurements for the identification and characterization of pyroxene grains embedded in polymorphous rock matrices.

Alluvial fan exhibits various modal distribution of pore-throat size, which effectively control the oil displacement efficiency and fluid movement. However, the genetic mechanism of the modal distribution of the pore-throat size and its macroscopic distribution within alluvial fan is poorly understood. Based on core analysis, this paper, which take the sandy conglomerate reservoir within the alluvial fan in Junggar Basin as an example, aims to study the variations in modal distribution of pore-throat size and controlling mechanisms. The results reveal that (1) The modal distribution types of the pore-throat size are complicated, and can be classified into six subtypes, including unimodal type Ⅰ (Uni-Ⅰ), unimodal type Ⅱ (Uni-Ⅱ), unimodal type Ⅲ (Uni-Ⅲ), bimodal type Ⅰ (Bi-Ⅰ), bimodal type Ⅱ (Bi-Ⅱ) and multimodal type (Multi). Uni-Ⅰ, Uni-Ⅱ, and Uni-Ⅲ is dominated by intergranular pores, intragranular dissolved pores and micropores, respectively. Bi-Ⅰ, Bi-Ⅱ and Multi are characterized by the combination of several pore types. (2) Diagenesis, including compaction, cementation and dissolution, rock composition (the mudstone fragment content) and rock texture (the clay content) control the volume of each pore-throat type, which significantly influences the modal distribution of the pore-throat size. Lithofacies with low mudstone fragment and clay content and great grain sorting tend to have experienced weak compaction, thereby retaining a large volume of intergranular pores, and have been subjected to strong dissolution when adequate acidic ions occur in the porewater, resulting in a large volume of intragranular dissolved pores. Strong dissolution reduced the rock compressive strength, and further enhanced the degree of mechanical compaction during the burial process. Cementation occurred later than compaction and dissolution, and its intensity is controlled by the supply of CO 2 and Ca2+ and compaction intensity, thus reducing the volume of intergranular pores. The content of mudstone fragment and clay varies among different lithofacies of different origins. For traction current deposits, lithofacies with smaller median grain size contain fewer mudstone fragments, resulting in fewer micropores. The clay content decreased first and then increased with decreasing median grain size, and lithofacies with lower clay content cause less volume of micropores. (3) Lithofacies types, combined with porewater condition for dissolution and lithofacies location, affect the diagenetic intensity, rock composition and rock texture variations, thus resulting in various modal distribution of pore-throat size within the alluvial fan. Moreover, the rock texture, especially grain sorting, is very important for compaction, and facilitates percolation of meteoric water and dissolution. • The modal distribution of pore-throat size of the sandy conglomerates within alluvial fan is complicated. • Lithofacies types, combined with porewater condition for dissolution and lithofacies location, affect the diagenetic intensity, rock composition and rock texture variations, thus resulting in various modal distribution of pore-throat size within the alluvial fan depositional system.

The 3D lithological distribution model presented in this data article is related to "Stochastic modeling of 3-D compositional distribution in the crust with Bayesian inference and application to geoneutrino observation in Japan" by Takeuchi et al. (2019) [1]. Our target region is set to the crust and uppermost mantle beneath Japanese main islands and their vicinity. We discretized the target region into 79,968 grid points. We defined 31 rock types; 29 major crustal rock types, plus sediment and mantle. Our lithology model represents a probabilistic distribution map inferred from a seismic tomography model and allows quantitative studies with error estimations, making it fundamentally different from previous models. To enable such quantitative applications, we provide explicit numerical data for the probabilities of the 31 rock types for each grid point. We also provide explicit values of the bulk proportion lithology model at various depths and for the bulk whole crust. Further, a figure of synthetic gravity data is presented to correct a minor error in the related paper [1]., (© 2019 The Author(s).)
