The compositional carbon isotopic series δ13C-CH42.4%. Where 2.4%>Ro>2.0%, almost all gases display partial isotopic reversal, with δ13C-CH4>δ13C-C2H6 or δ13C-C2H6>δ13C-C3H8. Carbon isotopic reversal in coal-derived gases is not caused by abiotic origin,

Abstract Conventional beamforming of multi‐component ambient seismic noise typically utilizes only the vertical‐vertical (ZZ) component to extract Rayleigh wave dispersion curves or the transverse‐transverse (TT) component for Love waves. In this study, we extend weighted and modified beamforming to cross‐correlation functions between different ...

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.

Drivers of ecological environment changes in the Baozhainao lake-basin system, Ordos Basin
In arid and semiarid regions, lake-basin ecosystems are an important part of watershed security barriers, playing an important role in maintaining the stability of ecological patterns. However, the ecological environment of the lake-basin system has been gradually degraded in recent years, and its change process is accompanied by a complex dynamic ...

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Dynamic conditions of Mesozoic petroleum secondary migration, Ordos Basin
Abstract: Tectonic movement of the Ordos Basin is characterized by the whole ascending and descending. The main driving forces of petroleum migration in the Mesozoic are buoyancy and abnormal pressure. The continuous oil column height in reservoirs of the Jurassic Yan'an Formation is close to the calculated oil column height required to overcome ...
