Quartz sand is the most common

diagenesis forms porcelanite

The collector then goes out with his ATV

It’s interesting to see quartz points offered in 50 gram lots on the Internet

Subsequent hydrothermal activity fills these voids with mineral-rich hot water and as it cools

kaolinite - soft white kaolin - large hand/display specimen of the primary constituent of kaolin clay Quartz sand is the mostkaolinite Al2(Si2O5)(OH)4 Kaolinite is the primary constituent of kaolin clay and is one of the kaolin group of minerals. Its physical structure is like a sandwich, with aluminum hydroxide layers, called gibbsite layers, bonded to silicate sheets. These sheets are electrically neutral, so they are bonded by very weak van de Waals forces, easily sliding apart to give kaolinite its usual softness and greasy feel. It has a similar structure to minerals
