Sandstone. 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.

Quartz Sandstone

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 process during abrasion is not ...
