Marine redox conditions and their dynamic changes were a major factor that controlled the formation of black shale and caused the late Ordovician marine extinction in the Upper Yangtze Basin (South Ch
Sedimentary uranium (U) and thorium (Th) isotopes are invaluable proxies to assess paleo export productivity and bottom water redox conditions, site-specific sediment focusing and vertical rain rates.
The composition of seawater changed dramatically during the initial rise of atmospheric oxygen in the earliest Paleoproterozoic, but the emerging view is that atmosphere-ocean system did not experienc
The International Ocean Discovery Program (IODP) Expedition 349 recovered Miocene oceanic red beds overlying the basaltic basement in the South China Sea. The occurrence of oceanic red beds provides a
The foraminiferal iodine-to-calcium proxy (I/Ca) can be used to reconstruct regional iodine speciation and redox conditions. This dataset contains new planktonic foraminiferal I/Ca measurements from m
