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 Jinshajiang Ocean and its adjacent area. Vacancy prediction, exploration and prospecting were carried out according to orebody type, reserving condition and country rock characteristics.
