Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.Overview.

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).2.1.4.1 Material Composition. The matrix materials in the deformable porous media are made up of either one single mineral or several minerals. For example, quartz sandstones are mainly composed of quartz (SiO2), while greywacke is composed of quartz, feldspar, mica, clay, and other minerals.
