Discussion on the characteristics and controlling factors of differential enrichment of shale gas in the Wufeng-Longmaxi formations in south China

Journal of Natural Gas Geoscience, 2020
Abstract The annual output of shale gas from the Wufeng-Longmaxi formations in South China reached 15.4 × 109 m3 in 2019, which makes Sichuan basin the second-largest shale gas producing area in the world. Based on the data of more than 1000 shale samples of the Wufeng-Longmaxi formations taken from typical drilling and outcrop profiles in the ...

Middle Neoproterozoic (Tonian) Polar Wander of South China: Paleomagnetism and ID‐TIMS U‐Pb Geochronology of the Laoshanya Formation

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 4, April 2024.
Abstract Paleomagnetic records of middle Neoproterozoic (820 to 780 Ma) rocks display high amplitude directional variations that lead to large discrepancies in paleogeographic reconstructions. Hypotheses to explain these data include rapid true polar wander (TPW), a geomagnetic field geometry that deviates from a predominantly axial dipole field, a ...
