Large amounts of conventional gas resources originated from terrestrial Lower Jurassic shale were discovered in Tarim Basin, indicating promising exploration prospects for shale gas resources, whereas limited understandings were obtained on the geological and geochemical characteristics of the Lower Jurassic shale In this study, based on cores of exploration wells and field outcrops, TOC pyrolysis, microscopic composition, organic elements, vitrinite reflectance, X-ray diffraction and methane isothermal adsorption experiment were carried out on Lower Jurassic shale in Tarim Basin. The results ...

The East China Sea (ECS) is featured by the broad continental shelf, huge terrigenous sediment input and striking river-sea interaction during the Quaternary. Despite the numerous studies, mostly on the delta, coastal and inner shelf areas, the late Quaternary stratigraphy and sedimentary environment on the mid-outer ECS shelf were poorly documented. In particular, it is still controversial in issues such as the recognition of marine transgression deposits in the interglacial period and the occurrence and ages of deposits in the glacial period. This study presents new data of high-resolution s...
