Mar 25, 2021 · The Zhangjiatan shale of Yanchang Formation is not only regarded as an important source rock in the Mesozoic, but also treated as a crucial target for shale gas exploration (Yuan et al. 2015). Previous studies have shown that the organic matter types of Zhangjiatan shale are mainly type I and type II (Guo et al. 2018 ; Ko et al. 2017 ; Hackley ... The Quaternary mantle comprises eolian deposits (quartz sand and silt), alluvium (gravel, sand, and silt of variable composition), colluvium, and a few landslides. At the mountain front, north-trending, dipping Paleozoic and Mesozoic sandstone, shale, and limestone bedrock formations form hogbacks and intervening valleys.

Mar 2, 2023 · Two lithofacies assemblages are identified in the Chang 7 Member. The assemblage composed of clayey shale, laminated silty shale, quasi-laminated silty shale, and laminated argillaceous siltstone lithofacies mainly occurs in the deep-water sedimentary environment of the semi-deep–deep lake facies in the lower Chang 7 Member. Such particle has a size larger than a clay, but smaller than a grain sand: It is a silt size particle. Since this shale has some silt and minor lithic silt size particles, Vshale=100% but Vclay <100%, because Vsilt > 0%. The tiny total micro-porosity seen, fully traps unmovable water.
