Abstract

The Caijiaying Zn-Au deposit is mainly hosted in Proterozoic high-grade metamorphic rocks with marble lenses, with minor ores in Jurassic volcanic cover rocks. It contains skarn ores, breccia ores, banded/folded ores, and locally epithermal features along a major fault, suggesting different origins such as metamorphic, skarn and epithermal. We have found that the breccia ores and the banded/folded ores are part of the skarn system, and the epithermal features may have formed in a later event. Gold is related to Bi minerals and may have been collected and transported by Bi melts. The location of orebodies is controlled by marble.
