The absence of regional electrical data has constrained our comprehension of the deep geological structures in the Jizhong Depression. This limitation has impeded the exploration of factors and principles governing geothermal reservoirs. Historically, studies on these factors primarily centered on geothermal field attributes, such as anomalous geothermal flux, geothermal gradients, and deep Moho variations. In our research, we undertook an exhaustive interpretation of extended-period magnetotelluric readings. This was amalgamated with prior regional geological and geophysical studies to discern deep geological structural details pertinent to geothermal resource components, encompassing heat sources, pathways, reservoirs, and cap rocks. Our analysis spanned the foundational surface of the Cenozoic era, fault configurations, carbonate formation distribution, and layers with low velocity yet high conductivity. We also statistically evaluated geothermal wells, their density, and the water temperature attributes across various structural entities. This aided in comprehending how structural units influence thermal well features. Our research delineated the spatial interrelation between geothermal well distribution and deep geological structures, including carbonate rock distribution, Cenozoic thickness, fault patterns, and profound low-velocity, high-conductivity layers. Moreover, we scrutinized how structural unit types impact thermal well attributes, offering insights into the formation principles of deep carbonate geothermal reservoirs within the Jizhong Depression. Our findings suggest that the genesis of deep geothermal resources in the Jizhong Depression is swayed by regional geological conditions. Notably, the distribution of regional and especially deep geothermal wells is intimately tied to regional stratigraphy, structural designs, and profound geological structural traits. Furthermore, the temperature within geothermal wells correlates strongly with the burial depth, carbonate formation thickness, Cenozoic thickness, and proximity to fault channels responsible for fluid movement and heat transmission.

Interfacial zones straddling terrestrial and marine realms, colloquially known as mudflats, epitomize a dynamic nexus between these environments and are fundamental to the coastal ecosystem. The investigation of these regions is paramount for facilitating infrastructural developments including ports, wharfs, cross-sea bridges, and the strategic utilization of freshwater resources sequestered from mainland islands amid ongoing economic progress. Terrestrial realms conventionally employ electromagnetic techniques as efficacious modalities to delineate subterranean geological information, encompassing structural details and water-bearing strata. However, the peculiar topographic and geological nuances of mudflat regions pose substantial challenges for the efficacious application of electromagnetic methodologies. The present paper endeavors to address these challenges by suggesting innovative modifications to the existing instrumentation and evolving novel data acquisition techniques specifically tailored for electromagnetic exploration within mudflat environments. This paper delves into the electrical characteristics of water-bearing layers within mudflats, and ascertains details pertaining to the subterranean structure and the spatial distribution of fresh and saline water resources, through the holistic interpretation of a multitude of profiles.

The phylogeny of tits has been studied using various molecular markers, but their phylogenetic relationships remain controversial. To further investigate their taxonomic status and phylogenetic relationships, the entire mitochondrial genomes (mitogenomes) and five nuclear segments were sequenced from 10 species of tits and two outgroups ( Sylviparus modestus and Remiz consobrinus ), followed by the comparison of mitogenomic characteristics and reconstruction of phylogenetic relationship based on the different datasets. The results revealed the following: the mitogenomes of 10 ingroup tits, each 16,758–16,799 bp in length, displayed typical mitogenome organization and the gene order found in most previously determined Passeriformes mitogenomes; close relationships existed between Parus major and P. monticolus , between P. montanus and P. palustris , and between P. ater and P. venustulus ; and Pseudopodoces humilis was a sister group to P. spilonotus , P. cyanus , or the clade containing P. major and P. monticolus .

Shijiazhuang is located in the contact area between the Taihang Mountain Uplift and the Jizhong Depression of the North China Plain, adjacent to the eastern Taihang Mountain Fault. The major geothermal fields are located to the southeast of the Shijiazhuang region. Considering that the origin of these geothermal fields can be better delineated via geophysical methods, in this study, broadband magnetotelluric data were acquired from 51 stations. The aim of this study was to understand the underlying mechanism of the action of a geothermal system in terms of resistivity and other known information. Before inversion, the data were processed via remote reference technique, and the dimensionality and geoelectric strike directions were analyzed. 2D inversion of the TM-mode data was performed via the non-linear conjugate gradient method, and a deep electrical structure was imaged. Combining the data with previous data, the tectonic units and fault distribution of study area were comprehensively interpreted. The four components of the geothermal system have been identified: a heat source, channel, thermal reservoir, and caprock. The low-resistivity layer in the middle crust was considered as a deep heat source, and the fault was a heat diffusion channel. The high-porosity carbonate rock in the uplift area was considered as a thermal reservoir, and the overlying Neogene and Quaternary strata were considered as caprocks for thermal insulation. This study provides valuable reference basis for studying geothermal fields in this area. • A magnetotelluric profile was obtained in the southeast of Shijiazhuang. • There is a mid-crustal low resistivity layer below 10 km in this region. • The results of MT clearly reflect the structures and fault distribution of the study area. • The study area's deep geothermal geological model was constructed.
