Silica mineral - Origin and occurrence | Britannica

Quartz is the least soluble of the forms of silica at room temperature. In pure water its solubility at 25 °C is about 6 parts per million, that of vitreous silica being at least 10 times greater. Typical temperate-climate river water contains 14 parts per million of silica, and enormous tonnages of silica are carried away in solution annually from weathering rocks and soils.
