| 摘 要： | 青海省东昆仑野马泉铁多金属矿床处于野马泉—开木棋河华里西期铅、锌、钴(金、锑、锡、铋)成矿亚带中,矿床规模达中型以上,是东昆仑地区重要的铁多金属矿床之一。通过分析矿床地质特征、矿体特征、围岩蚀变及控矿规律,认为铁多金属矿的成矿受印支期中酸性侵入岩、热液蚀变和晚石炭世缔敖苏组碳酸盐岩建造的控制,已发现的矿体赋存于岩体外接触带及附近的断裂带中,远离接触带铁矿体的规模逐渐变小,具有夕卡岩型矿床的基本特征。依据控矿因素特点,探讨了该类铁多金属矿床的勘查模型。

| Abstract: | Yemaquan Fe-polymetallic deposit is one of the major similar deposits located in Yemaquan-Kaimuqihe Hercynian Pb-Zn-Co(Au, Sb, Sn, Bi ) mineralization sub-belt, East Kunlun. Analysis of characteristics of the deposit geology, ore bodies and wall-rock alteration and ore-control factors show that the deposit is controlled by Indo-Chinese intermediate-acidic intrusive rock, hydrothermal alteration and late Carboniferous carbonatite formation. Ore bodies known are located at outer contact zone of intrusive body and in fractural zone near the contact. Farer away from the contact ore body tends to be smaller and characterized by skarn deposit. According to the ore-control factors it is built prospecting model of the deposit in the area. |
