Paleoenvironmental Reconstruction and Organic-Matter Enrichment Mechanisms of Marine Shale from the Ordovician Wulalike Formation, Northwestern Ordos Basin
The marine shale of the Ordovician Wulalike Formation in the northwestern Ordos Basin is an important target for shale gas exploration in northern China. The shale is thermally mature to locally highly mature, and generally has relatively low total organic carbon (TOC) and gas contents. Consequently, the paleoenvironme...
