Important occurrences are known in Udaipur, Dungarpur, Alwar, Ajmer and Pali districts.

Oxidation in Metals: Mechanism & Kinetics | Corrosion

Oxidation is a type of corrosion involving the reaction between a metal and air or oxygen at high temperatures in the absence of water or an aqueous phase. It is also called dry-corrosion. At normal temperatures, the oxides of the metals (except gold) are more stable than the metals. Metals being in the metastable state are bound to form oxides.
