Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic …

11.2.3 Effect of grain hardness. The main mineral in sandstones, quartz, is fairly hard, with H=7. Feldspar is less hard (H ~ 6) and less abundant. The main phases in chondrules and chondrites have similar hardness: olivine with Fe/Mg~0.1 has H=7, whereas enstatite has H ~5, and iron has H ~4.5. However, iron is malleable, so the rounding ...
