The silica origin of the shale samples from the Niutitang Formation is mainly biogenic, with no obvious hydrothermal or terrestrial clastic sources. TOC content in shale is high (>2%), resulting in the development of organic pores dominated by macropores, which leads to increased shale specific surface area and further strengthens the shale ...Shale is any fine clastic sedimentary rock that exhibits fissility, which is the ability to break into thin slabs along narrowly spaced planes parallel to the layers of stratification.

The 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. interbedded with shale and a subjugated amount of sandstones (Ori Tendency to chemical cement.
