Chemical weathering of minerals into clay
WebChemical weathering: The disintegration of granite - Increase surface area (physical) Dissolve minerals and cement (chemical) and alter hard minerals into soft minerals (chemical). - Olivine sand = Rare. Quartz sand = very common - Weathering transforms nearly everything into quartz, feldspar, and clay. WebClay minerals most commonly form by prolonged chemical weathering of silicate-bearing rocks. They can also form locally from hydrothermal activity. [14] Chemical weathering …
