Paleoenvironment reconstruction and differential OM enrichment mechanism of the Upper Triassic Chang 7 member source rocks in the Ordos Basin

Abstract The organic-rich mudstones within the lacustrine deposits of the Chang 7 member in the Ordos Basin are recognized as the primary source rocks of the Mesozoic petroleum system. Previously, scholars have extensively investigated the formation processes of high-quality source rocks in the deep...
