Gold Deposits in Skarn
July 2003
Skarn consists of coarse-grained calcium, magnesium, iron, and aluminum silicates formed by hydrothermal solutions, which replace limestone or dolomite near the contact with an igneous intrusion. The contact metamorphism is usually caused by an intrusion such as quartz monzonite, granodiorite, or similar rock type, which may or may not be mineralized.
