“…The southern North China Basin is located in the southern part of the North China Craton and the northern margin of the Qinling-Dabie Orogenic Belt . This basin bounded by the Sulu Ultrahigh Pressure Metamorphic Belt and the Tan-Lu Fault in the east is a Meso-Cenozoic superimposed basin developed based on the late Paleozoic craton basin (Figure a). , The Pingdingshan coalfield is located in the Zhoukou Basin in the west of the southern North China Basin, and its main structure is a large syncline (Likou syncline, Figure a,b) . A series of NW-axial folds and NW-trending tensile and compression–torsional faults are developed, accompanied by a small amount of NE tensile and torsional faults.…”

“…The coal measure in the Pingdingshan coalfield belongs to the stratigraphic unit of the North China type. 39 This coalfield is based on the Archean and early Proterozoic metamorphic rock that underwent complex structural deformation. Except for the absence of sedimentary records from the early Ordovician to the early Carboniferous for about 100 Ma, there are no sedimentary records in this area in the Triassic, Jurassic, and Cretaceous periods.…”

“…The coal-bearing strata belong to the Permian-Carboniferous system, covering an area of 650 km 2 . The Shanxi coal-bearing strata are regarded as target source rocks in the Pingdingshan coalfield with considerable gas resources. − However, the sedimentary process and hydrocarbon generation potential of source rocks in the Shanxi Formation are still unclear. Therefore, the primary objective of this study is to reveal the formation and evolution of source rocks of the Permian Shanxi coal measure and their hydrocarbon implications.…”

Coal measures, widely developed in the marine–continental transitional environment, have been regarded as an important reservoir of petroleum resources, such as coalbed methane, shale gas, and tight sandstone gas. In this study, petrography, organic geochemistry, and isotope geochemistry were conducted to reveal the organic matter sources, maturation, and paleoenvironment of Permian coal-bearing source rocks in the Pingdingshan coalfield, China. Organic petrography indicates that the organic matter of the Lower Shanxi shales are derived from the terrigenous and marine mixed inputs and those of the coals are mostly sourced from terrigenous input. Thermal parameters suggest that the source rocks of the Lower Shanxi Formation reached the late oil generation stage (∼1.06% R o), and that of the Upper Shanxi Formation entered the early oil generation stage (∼0.87% R o). Geochemical results suggest good hydrocarbon potential of all coal samples but poor potential of most mudstones and shales. The generated hydrocarbons generally originate from the in situ source rocks, and no obvious migrated hydrocarbons exist due to the low production indexes. δ13C and δ15N values of coals are significantly more negative than those of mudstones and shales, suggesting that the plants flourished with efficient photosynthesis and the coals experienced intense microbial nitrogen fixation during the coal-forming period. Rapid propagation of terrestrial plants leads to the increase of carbon fixation by photosynthesis and the enrichment of 13C in the atmosphere. The increase of the sea level may lead to the massive burial of terrestrial plants in peat swamps, which decreases the photosynthesis and increases nitrogen fixation, resulting in the depletion of 13C in the atmosphere and the enrichment of 15N in organic matter.

“…As a large coal-accumulating sedimentary basin in the foreland of the Qinling-Dabie Orogenic Belt, Pingdingshan coalfield possesses significant coal and geothermal resources, and its coal rank is mainly dominated by medium metamorphism coal, indicating a particular effect of tectono-thermal events. − This coal rank was also controlled by anomalous geothermal fields and regional magmatic intrusions in the Pingdingshan Coalfield. The primary coal-bearing source rocks associated with rich geothermal resources are developed in the Carboniferous-Permian Taiyuan and Shanxi Formations.…”

As an important energy base in central China, the Pingdingshan coalfield has abundant coal and geothermal resources. The cooperative exploration of coal and geothermal resources is significant for the comprehensive utilization of energy resources. This work collected coalbearing samples from the Pingdingshan coalfield to investigate the tectonothermal evolution of a high geothermal coalfield, especially the present geothermal field and hydrocarbon generation model. The geochemical results show that the Shanxi and Taiyuan source rocks have average R o values of 0.88 and 0.97%, respectively, with an average Rock-Eval T max value of 442 °C. Hydrocarbon generation of source rocks started at ∼205 Ma, with the highest rates at ∼170 Ma, reaching the maximum transformation ratio of 40−50% in the middle of the Early Cretaceous. The age and length of apatite fission tracks (AFTs) indicate that coal-bearing strata underwent significant postdepositional annealing after the Late Permian and suggest an abnormal thermal event that occurred in the Late Mesozoic. Meso-Cenozoic thermal event was mainly caused by the plutonic metamorphism of the Early Jurassic and magmatic thermal metamorphism of the Early Cretaceous, achieving a maximum paleotemperature of ∼140 °C. The magmatic thermal event resulted from the intensive post-orogenic extension of the Qinling-Dabie Orogenic Belt caused by the tectonic transition of the North and South China Plates. The present-day high geotemperature of Pingdingshan Coalfield is dominated by the horst structure caused by the regional extension of the basin-mountain system. The Cambrian limestone with a high thermal conductivity underlying coal measure collects deep heat, forming a heat accumulation center of this horst structure with a heat flow of 74 mW/m 2 and a maximum temperature of ∼50 °C nowadays.

The chemical composition of the deep continental crust is key to understanding the formation and evolution of the continental crust. However, constraining the chemical composition of deep continental crust is limited by indirect accessibility. Here we present a modeling method to constrain deep crustal chemical structures from observed crustal seismic structures. We first compile a set of published composition models for the continental crust. Phase equilibria and compressional wave speeds (VP) are calculated for each composition model at a range of pressure and temperature (278-2223. Functional
