Redox-sensitive trace metals have been used extensively as geochemical proxies to infer
the redox-status of marine sediments at the time of their deposition, and by extension, the …

The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Existing redox classifications and the calibrations of elemental proxies to modern
environmental redox scales are in need of re-evaluation. Here, we review environmental …

With the urgent need to increase shale gas production and reserves, deep shale gas has
gradually become an important target for further exploration in China. However, there is still …

Abstract The Permian Chert Event (PCE) was an unusual global chert accumulation that
reflects tectonic–climatic–environmental changes during the late Paleozoic. South China …

The Wufeng organic-rich shale is widespread in the Upper Yangtze platform, and it is one of
the most advantageous shale gas producers in China. Its deposition commenced with the …

Abstract The Early Jurassic Toarcian oceanic anoxic event (T-OAE) is characterized by an
extinction event, a major sea-level rise, enhanced marine primary productivity, elevated …

A continuously cored well covering the Carboniferous-Permian Benxi, Taiyuan, and Shanxi
formations in the eastern Ordos Basin provides a rare window into environmental conditions …

The Neoproterozoic provides an important record of glacial–postglacial paleoenvironments,
organic carbon cycling, and hydrocarbon accumulation. Here, to better understand the …

Because of anthropogenic global warming, the world ocean is currently losing oxygen. This
trend called ocean deoxygenation is particularly pronounced in low-latitude upwelling …
