Gold can occur in Skarn deposits in grades that are economic. Skarns are typically formed at the contact of intrusive granitic magma and carbonate sedimentary rocks such as limestone or dolomite. They also can form where hydrothermal fluids react with limestone and form the skarn minerals such as amethyst, hedenbergite etc.

A recent paper by Prof. George P. Merrill, Curator of the Department of Geology of the U. S. National Museum, Washington, upon " An Occurrence of Free Gold in Granite," describes an interesting instance of the dissemination of this noble metal in the substance of granite of normal composition believed to be from Sonora, Mexico. He found the gold in small scales, rarely exceeding a ...

This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.
