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。
The Tianyinchang copper deposit is controlled by the interlayer crustal zone of the anticlinal core and its two wings. The ore features are dominated by limonite, malachite, azurite, and copper oxide, and gradually transition to the deep copper Mine, chalcopyrite, spot copper, tetrahedrite and other primary ore. Iron oxide cap is the most important prospecting symbol. Fluid inclusions and isotope studies show that the ore deposit belongs to the mesothermal hydrothermal deposit formed in the Himalayan period, and the ore-forming fluids originate from the deep, possibly related to magmatic hydrothermal fluids. The ore body may have a greater depth of extension. The deposit is located on the periphery of the famous large gold-bearing copper mine and has a good prospect of mineralization.
