Geochemical and isotopic (Re-Os and Mo) compositions of black shales from the Cumbum Formation, Cuddapah Basin, India

This dataset contains the geochemical (major element, trace element and Fe-speciation) and isotopic (Re-Os and Mo) compositions of black shales from the Cumbum Formation, Cuddapah Supergroup (India). This dataset was used to provide new constrains on the depositional age, setting and the extent of global euxinia during the depositional interval.
