Soapstone. Soapstone is a soft, dense heat resistant rock. The metamorphism of ultramafic protoliths forms it. Its primary component is talc with traces of chlorite and carbonates. Soapstone is suitable for curving because it is soft and heat resistant. 2. Precipitation from solution. What Is Sedimentation? Sedimentation is the combined name for all the processes that cause organic and mineral particles to settle. The particle that helps in forming the sedimentary rock is called sediment.Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size.

Slowing turbid currents drop their coarser fractions first (gravel and sand) and the finer silt and clay fractions settle out last. Figure 6.63. Appearance and example of graded bedding in sedimentary deposits. Graded beds will "fine-upward" as currents slow down.Sedimentary rocks like bituminous coal, limestone, and sandstone, given enough heat and pressure, can turn into nonfoliated metamorphic rocks like anthracite coal, marble, and quartzite.
