Weathering & Clay Minerals - Tulane University

Thus, rocks rich in feldspar commonly weather to kaolinite In order to form, ions like Na, K, Ca, Mg, and Fe must first be leached away by the weathering or alteration process This leaching is favored by acidic conditions (low pH) Granitic rocks, because they are rich in feldspar, are a common source for kaolinite...
