WebThe characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. Web1 Apr 2024 · 1. Introduction. Fine-grained sedimentary rocks, which are deposited in low-energy environments, account for 2/3 of the entire sedimentary sequences, and they are both source rocks and effective reservoirs for unconventional petroleum systems (shale oil and tight oil play) (Aplin and Macquaker, 2011; Liu et al., 2024).The Lucaogou Formation in …
