【摘要】 青海省都兰县清水河位于青海东昆南金、铜、铅、锌、钴成矿带中段,区域上受北西向逆断层的控制,断裂引起的次级裂隙构造较为发育,断裂、裂隙构造成为矿液的运移通道和储存空间,控制了矿产的空间分布。通过考查区内地质背景和地质特征,分析矿体地质特征及控矿因素、矿床成因、找矿标志等,认为矿床在空间、时间上及成因上与中三叠世侵入岩英云闪长岩有关,岩浆的侵入不仅为成矿提供了热液的来源,也是有用矿质的重要来源。因此中酸性英云闪长岩侵入体是清水河矿床重要的控制因素。更多还原

【Abstract】 Qingshuihe,Dulan county,Qinghai province,is located in the middle of the gold,copper,lead,zinc and cobalt metallogenic belt in the east kunnan area of qinghai province.Controlled by northwest thrust fault,the secondary fracture structures caused by faults are relatively developed.The fracture and fracture structures become the migration channel and storage space of mineral fluids,which control the spatial distribution of minerals.Based on theanalysis of regional metallogenic strips,itis considered that the deposit is related to the middle triassic intrusive rockquartz diorife in space,time and genesis magma intrusion not only provldes a souece of hydrothermal solufion for mineralizafion,but also an important source of useful minerals.therefore the intermediate acid quartzife intrusion is an important controlling factor of the qingshuihe deposit.更多还原
