The Yangla copper deposit is located in the Jingshajiang joining part with north overturn of Jiaren magmatic rock body at Neopaleozoic-Early Mesozoic volcanic arc connecting part, the ore-bearing stratum resulted from volcanic-spouting sedimentary process, forming stratiform massive sulfide orebody. The intrusion of intermediate-acidic magmatic rock bodies superimposed on the original stratiform orebodies forming thick scarn type orebody and non-mineralized skarn composed of kalkgranat, asteroite, aktinolith and acanticonite etc. Northeast striking big vein orebodies were formed during late Indo-Chinese epoch and early Yanshan period, with part of the small type vein porphyry orebody being mainly superimposition ore deposit resulted from the structural evolution of
