Vesiculate amygdaloidal basalt stands out as a recently recognized primary reservoir within Urho area, the northwestern periphery of Junggar Basin. Notably, a significant proportion of the volcanic rock-type oil and gas reservoirs discovered in this region is affiliated with the volcanic formations of Hala'alate Formation. Within this stratigraphic unit, a distinct segment characterized by vesiculate amygdaloidal basalt exhibits remarkable development, encompassing over 78% of the total thickness of the strata. This particular interval serves as an optimal candidate for in-depth studies on volcanic rock reservoir characteristics. The amygdaloid bodies in these basalts predominantly consist of secondary calcite, which demonstrates a high solubility in water. These amygdaloid bodies often assume circular to semi-circular configurations, with many interconnected in patterns resembling networks, branches, or irregular structures. Statistical analyses corroborate that subjecting these amygdaloid bodies to dissolution in wellbore fluids results in a significant increase in porosity, approximately ranging from 3.6 to 4.5 times, effectively rendering them highly favorable as reservoir lithology. A robust assessment of the reservoir quality considers three distinct parameters, including stomatal unit area proportion, the proportion of connectivity, and the proportion of porosity enhancement stemming from amygdaloid dissolution. When all three of these criteria achieve excellence, the reservoir attains a classification of excellent reservoir. Meanwhile, a classification of favorable reservoir is attributed when a minimum of two criteria reaches an excellent level. A prudent estimation indicates that over 50% of the 110 samples obtained from a dataset surpass the established criteria for a favorable reservoir, thus demonstrating a noteworthy potential for reservoir development. The above reservoir division scheme provides a reference for establishing comprehensive evaluation scheme of evaluating the reservoir performance specific to vesiculate amygdaloidal basalts.

The southern structure of the Yining Plot brings out a large area of Late Devonian-Early Carboniferous magmatic rocks, and its formation is closely related to the evolution of the Southern Tianshan Ocean, and there are still disputes in terms of rock genesis and production environment. In the area of the Coksu Forest Farm in the southern tectonic belt of the Yining Plot, high-magnesium andesite rocks endowed in the volcanic rocks of the Lower Carboniferous Great halajunshan Formation were newly discovered, and detailed field geological surveys and indoor analysis work were carried out, and the tectonic background of the period was explored. The results show that the rock types of the Great Hara Junshan Formation in the area are mainly Andesan rocks, containing a small amount of basalt and volcaniclastic rocks. The andesan samples had high MgO, TiO, AlO content, low PO content, and Bitman index, showing the characteristics of medium-high potassium calcium alkaline series rocks, combined with their high Sr, Y content and low Ni and Co content, and low Sr/Y, La/Yb values, showing the geochemical characteristics of Sanqi high magnesium andesite rocks; The total content of rare earth elements in the samples varied widely, with high (La/Yb), (La/Sm) and (Gd/Yb) values, showing significant enrichment of light rare earth elements; The samples enriched large ionic lithophilic elements such as K, Ba, Th, U, and Pb, and the relative loss of high field strength elements such as Nb, Ta, Ti, and P, and negative Eu anomalies. Combined with regional data, it is believed that these Zamgi high magnesium andes rocks originate from the equilibrium reaction of mantle wedges and subduction zone materials, and are the products of the late Devonian-Early Carboniferous Southern Tianshan Ocean subducting northward under the southern tectonic belt of the Yining Massif. The discovery of high-magnesium andesites not only enriches the rock types in the area, but also provides an important reference for solving the problem of regional tectonic evolution [ABSTRACT FROM AUTHOR]

As one of the largest Phanerozoic orogens in the world, the Central Asian Orogenic Belt ( CAOB) is an excellent place for studying accretionary orogenic process and continental crust growth. It is widely accepted that the CAOB formed by long-lived evolution of the Paleo-Asian Ocean (PAO) from Neoproterozoic to Early Mesozoic, comprises various allochthonous fragments, such as micro continents, island arcs, seamounts/ oceanic plateaus, accretionary prisms, and ophiolitic melanges. The composition of ophiolitic melange is almost same in the western CAOB. Except the typical ophiolite components, the ophiolitic melanges contain pillow basalt, volcanic breccia, reef limestone, olistostrome, and terrestrial elastic rocks. Geochemically, the mafic rocks in ophiolitic melange can be divided into two groups of MORBand OIB-type. The MORB-type belongs to tholeiitic basalt series and shows subduction characteristics; the OIB-type belongs to alkaline basalt series, and is formed in seamount/ oceanic plateau affinity. The age, property and distribution of ophiolitic melanges and metamorphic rocks in the western CAOB indicate that the subduction initiation time of the PAO is no later than Early Neoproterozoic, and the locat ion should be on the southern margin of Siberia plate and gradually develop southward. In the early development of the PAO, the mechanism of subduction initiation should be mantle plume-induced dominant. However, in the later period, the seamount/ oceanic plateau may block the subduction channel, causing the subduction polarity reversal and transition, and the subduction initiation occurs. Initiation of new subduction zone is a difficult problem of Earth's plate tectonics regime. The reason is that the subduction initiation is an extremely short process, scarcity of geological record, and there are few cases of subduction initiation that are happening on Earth today. Therefore, it is necessary for geologists to work together to reveal the past and present lives of the PAO, and to solve the mystery of the subduction initiation of plate tectonics.

The Yining Block is an important part of the West Tianshan orogenic belt. There are many Late Paleozoic volcano-magmatic rocks and sedimentary formations exposed on this block, which is of great significance to decipher its formation and evolution. The Yining Block can be divided into two tectonic units, namely the south and north, bounded by Wusun mountain-Taled fault in EW direction at the central part of the block. They are significantly different in basement construction, composition and age of magmatic rocks, geochemical characteristics, basin formation and tectonic evolution. The south tectonic belt is composed of Dahala-Kalajun island arc zone and Atengtao back-arc extensional basin from Late Devonian to early Early Carboniferous, with the trench being located in the south of the island arc zone (near the southern margin of Nalati fault); the north tectonic belt consists of Awulale superimposed island arc zone, Tekes-Xinyuan fore-arc basin, Qingshuihe-Subutai back-arc basin and fan delta in the middle and late Early Carboniferous. On the basis of resorting and summarizing the latest division scheme of Yining Block, a new understanding of the formation and evolution of Yining Block, namely two collages and three-stage evolution on the two tectonic belts, is put forward for the first time. The detailed processes include: 1) from Late Devonian to early Early Carboniferous, the initial arc-basin system is primarily formed in the south tectonic belt; 2 during the middle and late Early Carboniferous, the trench-arc- basin system in the north tectonic belt is generated and superimposed by the other belt; 3 in the early Late Carboniferous, the initial south tectonic belt and the accretionary north tectonic belt are collaged and sutured, completing the collision and accretion of this block. These processes result in the formation of the unified Yining Block. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of bone cemented and biological prostheses hemiarthroplasty on postoperative trauma and bone metabolism in the elderly patients with femoral neck fracture. Methods 60 elderly patients with femoral neck fracture who have underwent hemiarthroplasty in our hospital from January 2018 to January 2020 were selected and divided into cemented type group and biological type group with 30 cases each according to prosthesis type. The levels of inflammatory factors [ tumor necrosis factor-α ( TNF-α), interleukin-6 (IL-6), procalcitonin (PCT), C- reactive protein (CRP) ], stress hormones [ norepinephrine (NE), epinephrine (E), cortisol (Cor) ], bone metabolic markers [ type I collagen carboxy-terminal peptide [3 special sequence (β-CTX), total type I collagen amino-terminal elongation peptide (tPINP), bone alkaline phosphatase (BALP), whole-segment parathyroid hormone (iP TH) ] were compared between the two groups on preoperative and the 1st and 7th day after operation. Results The levels of inflammatory factors (TNF-α, IL-6 PCT CRP) and bone metabolism (β-CTX, tPINP, BALP, iPTH) were not statistical significance between the two groups (P > 0. 05) on preoperative and the 1st and 7th day after operation. The levels of stress hormone (NE, E, COR) between the two groups were not statistical significance on preoperative and the 7th day after operation (P > 0. 05), but on the 1st day after operation (P < 0. 05). Conclusion There is no difference in inflammatory factors and bone metabolism between the two prosthesis surgeries for elderly patients with femoral neck fracture. However, biological prostheses have little effect on stress hormone and have more advantages for patients with many basic diseases and poor surgical tolerance. [ABSTRACT FROM AUTHOR]

Hatu pluton in the southern margin of West Junggar invades into Early-Middle Devonian marine volcanic-sedimentary strata. The lithology of Hatu pluton is mainly composed of monzonitic granite, syenite granite and a small amount of alkali feldspar granite, which is an ideal object to study the tectonic setting of Late Carboniferous in West Junggar. The granites in Hatu pluton have high SiO2(72.06%-76.53%), Na2O+K2O(7.80%-8.57%)and Al2O3(12.55%-14.06%)contents, low CaO(0.20%-1.58%)and MgO(0.07%-0.42%)contents, with A/CNK(1.06-1.15)and A/NK(1.15-1.36)showing the characteristics of weakly peraluminous-strongly peraluminous granite. The granites have high total contents of REE((88.14-139.53)×10-6)and ratios of LREE/HREE((La/Yb)N is 3.04-6.50), and the chondrite-normalized REE pattern exhibits a typical right-dip “V” shape with a strong negative Eu anomaly, indicating that some plagioclases may be retained as a residue in the source area or there is the separation and crystallization of plagioclases. Meanwhile, the granites display significant enrichments of large ion lithophile elements(Rb, Th, U, K and Pb), relative enrichments of Zr and Hf, and depletions in Ba and Nb, especially Sr, Ti and P. The above characteristics demonstrate that Hatu pluton is a typical weakly peraluminous-strongly peraluminous A2-type granite. Combined with diagrams of major and trace elements, Hatu pluton in West Junggar is formed in a post-orogenic extension setting, and the petrogenesis is related to the juvenile crust that comprised both oceanic crust and island arc, which results from partial melting and fractionation under low pressure condition.

The high-alumina basalts of Lower Devonian Tuoranggekuduke Formation occur in Yematan of Qinghe area, East Junggar, China. The high-alumina basalts are rich in a large number of plagioclase phenocrysts, belonging to a sub-alkaline series. The basalts have significantly high A12O3 (the mass fraction is 17.22%-21.31%), low SiO2 (47.12%-49.45%), and high TFe2O3 (8.50%-11.98%), MgO (2.64%-5.63%), Ni ((5.75-27.87)×10-6), Cr ((0.99-25.62)×10-6), and high Sm/Yb ratio (1.13-1.96), U/Th ratio (0.42-0.81), and they relatively enrich in large ion lithophile elements and deplete in high field strength elements, indicating the characteristics of the typical geochemical features of high-alumina basalts. The further research shows that the magma is derived from the partial melting of the mantle wedge modified by the subduction zone fluid. In addition, the basalts with high Sr/Y ratio (43.16-47.07), low Y (the mass fraction is (15.69-19.09)×10-6) and Yb ((1.64-2.13)×10-6) indicate that the source of basaltic magma may contain subduction zone oceanic crust materials. The characteristics of high Al are likely to be related to the delayed crystallization of plagioclase under high pressure conditions. Geochemical characteristics indicate that these high-alumina basalts are formed in an island arc environment. The discovery of Early Devonian high-alumina basalts enriches the petrographic data of volcanic rocks in East Junggar and provides an important basis for the study of tectonic evolution.

Basaltic magma, which is found in whole process of plate tectonic evolution and the critical stages, is a most important tectonogeochemical indicator in all igneous rocks. Therefore, the diagrams and ratios of related elements in basalts become the first choice to investigate the igneous diagenesis and tectonic setting. Ta, Hf, Th, La, Zr and Nb, which are high-field strength elements and stronger incompatible elements, have similar geochemical properties and regular changes in basaltic diagenesis, thus, they are most frequently used in basalt genesis and discrimination diagrams of tectonic setting. Moreover, the ratios of contents between the each one of elements can better distinguish the tectonic settings of formation. Based on the double-log discrimination diagrams of Th/Hf-Ta/Hf, Th/Zr-Nb/Zr and La/Zr-Nb/Zr in basalt yielded by previous research, the ratios of Ta/Hf, Th/Ta, Th/Hf, Nb/Zr, Th/Nb, La/Nb values were proposed to distinguish the basalts in various common tectonic settings, and the ratio discrimination table was put forward. The table extremely distinguishes basalt in most common variety of tectonic environments and is a great supplement for the double-log discrimination diagrams. [ABSTRACT FROM AUTHOR]
