Geological Characteristics and Mineralized Prospect of Tianyinchang Copper Deposit in Lanping,Yunnan Province

Tianyinchang copper deposit is in the charge of interformational fracture zone between the two limbs and the core of the anticline,ore characteristics of superficial part are mainly limonite,malachite,azurite,covellite,then gradually transited to deep to primary ore,such as chalcocite,chalcopyrite,bornite,tetrahedrite,etc.Oxidized gossan is the most important Prospecting Criteria.Fluid inclusions and isotope research suggest that deposits is mesothermal deposit of Himalayan period.Ore-forming fluid is derived from deep,may be related to magmatic hydrothermal and the ore bodies may extending to the depth.The deposit is located in the surrounding of the famous JinMan large-scale copper deposit and has good prospecting perspective.
