中文摘要: |
宁夏香山砂(页)岩型铜矿,呈层状、似层状,主要产于泥盆系上统老君山组第二岩段(D3l2)上部。铜矿物主要为孔雀石、蓝铜矿、辉铜矿、黄铜矿。铜矿石中伴生银。成矿部位为内陆湖盆边缘带,成矿环境为强氧化向弱还原转变的地球化学环境。通过探讨砂(页)岩型铜矿的成矿环境特征,提出了该区铜矿的找矿标志。该地区铜矿正在评价勘探,外围找矿正在深入开展中。 |
英文摘要: |
The sandstone copper of Xiang Mountain formed in the Dl2 of upper Devonian as a layered rock.Its minerals mainly are Malachite,Azurite,Chalcocite and Chalcopyrites,accompanying by some silver.The mineralizing position is in the side zone of an inland basin,where the geochemical environment is becoming from a strong oxidizing milieu to a reducing milieu.Through the discussion and researches on the geological features of the mineralizing environment of the sandstone copper,the ore-hunting indicators were put ... |
