Characteristics of sedimentary rocks are described in Pellant p. 38-41and 44-45; Marshak, p. 176-186. Texture: Sedimentary rocks may have clastic (detrital) or non-clastic texture. Clastic sedimentary rocks are composed of grains, fragments of pre-existing rocks that have been packed together with spaces (pores) between grains. These Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it’s called shale. Otherwise, it’s siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay)..
