Elemental potassium does not occur in nature because of its high reactivity. It reacts violently with water and also reacts with oxygen. [[Orthoclase]] (potassium feldspar) is a common rock-forming mineral. [[Granite]] for example contains 5% potassium, which is well above the average in the Earth's crust. [[Sylvite]] (KCl), [[carnallite]] ({{chem2|KCl*MgCl2*6H2O}}), [[kainite]] ({{chem2|MgSO4*KCl*3H2O}}) and [[langbeinite]] ({{chem2|MgSO4*K2SO4}}) are the minerals found in large [[evaporite]] deposits worldwide. The deposits often show layers starting with the least soluble at the bottom and the most soluble on top. Deposits of niter ([[potassium nitrate]]) are formed by decomposition of organic material in contact with atmosphere, mostly in caves; because of the good water solubility of niter the formation of larger deposits requires special environmental conditions.</div>FuzzyBot
