Origin of two differentiation trends in the Emeishan flood basalts

Chinese Science Bulletin, 2003
Both the Bowen and Fenner differentiation trends have been recognized in the Emeishan flood basalts. While the Longzhoushan lavas in Panxi paleorift evolved on a trend of silica enrichment (Bowen trend), the lavas from Guizhou evolved along the Fenner trend leading to the magmas with high Fe2O3 (23%) and low SiO2 (44%) contents.

Origin of hydrothermal deposits related to the Emeishan magmatism

Ore Geology Reviews, 2014
Abstract In the western Yangtze Block, southwest China, there are many hydrothermal native copper ore deposits and Zn–Pb ore deposits. All of these hydrothermal ore deposits are spatially associated with the Permian Emeishan flood basalts (EFBs), although they are much younger than the EFB.

Contrasting geochemical signatures on land from the Middle and Late Permian extinction events [PDF]

, 2014
The end of the Palaeozoic is marked by two mass‐extinction events during the Middle Permian (Capitanian) and the Late Permian (Changhsingian). Given similarities between the two events in geochemical signatures, such as large magnitude negative δ 13 C ...

Geological Controlling Factors of Low Resistivity Shale and Their Implications on Reservoir Quality: A Case Study in the Southern Sichuan Basin, China

Energies, 2022
At the Changning block and at the Luzhou block, the genetic mechanism of low-resistivity shale and its impact on reservoir quality are currently a hot topic on a world-wide scale. Shale with resistivity lower than 20 Ω·m is widely developed at the Wufeng-

An abrupt extinction in the Middle Permian (Capitanian) of the Boreal Realm (Spitsbergen) and its link to anoxia and acidification [PDF]

, 2015
The controversial Capitanian (Middle Permian, 262 Ma) extinction event is only known from equatorial latitudes, and consequently its global extent is poorly resolved.
