摘要
白银厂矿田及其外围 ,由南向北可划分为 3个成矿带。独立金矿床以冲洪积、坡残积砂金矿及砾岩型金矿为主 ;伴生金矿床主要与热液型铜及多金属矿床有关。矿床受北西西向区域性大断裂及其次级派生断裂控制 ,矿床与玄武岩、安山岩、石英角斑凝灰岩及某些酸性 -中酸性侵入岩体有关。苏家湾 -石青硐大断裂及其两侧、酸性 -中酸性浅成侵入体分布区及前寒武纪地层分布区是今后的找矿方向。
Baiyin mining area and its periphery can be devided in to three ore forming belts from south to north.Independent gold ore deposit mainly consists of alluvial and diluvial,slope wash sandstone and bibbley rock.The associated gold ore deposit is mainly related to hydrothermal copper or multimetal mineral deposit.The deposits are under the control of the north west west regional fracture and its proximate grade derived fracture and are related to basalt,andesite,quartz keratophyre taff and some acid or medium acid intrusive rock.The future orientation of mineral deposit exploration should be focused on the big Sujiawan-Shiqingdong fracture and its sides,acid-medium acid hypabyssal intrusive rock area and pre cambriam stratum area.
