摘要
天银厂铜矿受背斜核部及两翼的层间破碎带控制,矿石特征浅部以褐铁矿、孔雀石、蓝铜矿、铜兰等氧化物为主,向深部逐渐过渡到辉铜矿、黄铜矿、斑铜矿、黝铜矿等原生矿。氧化铁帽是最重要的找矿标志。流体包裹体及同位素研究表明,矿床属喜山期形成的中温热液矿床,成矿流体来源于深部,可能与岩浆热液有关,矿体延深可能较大。矿床处于著名的金满大型铜矿的外围,有较好的成矿远景。
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.
