Quartz Sandstone - an overview | ScienceDirect Topics

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 relevant.
