This study reports on the organic geochemical characteristics of high‐TOC shales in the Upper Triassic Zangxiahe Formation from a study area in the north of the Northern Qiangtang Depression, northern Tibet. A total of fifty outcrop samples from the Duoseliangzi, Zangxiahe South and Zangxiahe East locations were studied to evaluate the organic matter content of the shales and their thermal maturity...
Organic‐rich marine black shales and cherts of latest Proterozoic to earliest Cambrian age are widespread in South China. In this study, 70 samples of the Early Cambrian basal Niutitang Formation from Yangtiao (Guizhou Province, SW China) were analysed using organic and inorganic elemental and isotopic methods in order to characterize the depositional environment and source‐rock potential of these...
