Tracing Shale-Gas Migration in Complex Tectonic Settings: Evidence from Carbon-Isotope Fractionation Patterns

Abstract Late-stage tectonic deformation strongly influences shale-gas preservation and redistribution, but conventional methods rarely resolve gas-migration pathways and directions. Here, we test whether the direction of spatial carbon-isotope gradients can indicate the dominant...

Gas content, geochemistry and accumulation of coalbed methane in Suzhou mining area of the Huaibei coalfield, China

Abstract Coalbed methane (CBM) resources in the Huaibei coalfield, particularly within the Suzhou mining area, have garnered significant attention due to their substantial energy potential. This study investigated the gas content, geochemical characteristics, and accumulation mec...

Geochemical Evidence for the Evolution of the Deyang–Anyue Rift in the Ediacaran–Cambrian Period on the Northwestern Margin of the Yangtze Block

Abstract The evolution of a large intracratonic rift trough in the northern Sichuan Basin, China, along the northwestern margin of the Yangtze Block, is documented during the significant Ediacaran–Cambrian Transition (ECT). Three prevailing perspectives exist regarding the specif...
