Radiometric dating of marine-influenced coal using Re–Os geochronology [PDF]
Earth and Planetary Science Letters, 2015 Abstract Coal deposits are integral to understanding the structural evolution and thermal history of sedimentary basins and correlating contemporeous estuarine and fluvial delatic strata with marine sections. While marine shales may readily lend themselves to Re–Os dating due to the dominance of hydrogenous Re and Os, the lack of a chronometer for ...
