1. Introduction to Gossans Definition:Gossans are iron-rich, weathered outcrops formed by the oxidation and chemical weathering of sulfide-bearing mineral deposits. They appear as rusty, reddish-brown to yellow zones on the Earth’s surface and are critical indicators of potential subsurface mineralization. Formation:Gossans develop through the supergene alteration of sulfide ores (e.g., ...
