青海祁漫塔格冰沟南多金属矿矿化体地质特征分析

Geological Characteristics of Polymetallic Orebody in the South of Qimantag Binggou,Qinghai Province

冰沟南多金属矿位于青海省海西州茫崖镇祁漫塔格地区,成矿地质条件优越。在矿区南侧区域由呈北西向的昆北断裂进行横贯。区内分布着异常丰富的金、铜、铁、锌、铅多金属矿,是青海地区重要的多金属矿矿集区,除冰沟南多金属矿外,区内还分布着虎头崖及迎庆沟等多金属矿床,具有非常相似的成矿类型与成矿条件,该区狼牙山组地层与晚三叠世鄂拉山组火山岩的接触部位靠近狼牙山组地层一侧渗滤交代矽卡岩型铅锌铜多金属矿具有良好的找矿前景。

Binggou South Polymetallic Mine is located in Qimantag area,Baiya Town of Qinghai Province.It is with superior metallogenic geological conditions.In the south side of the mining area,the north-west-to-north Kun fault is transversal.The area is rich in gold,copper,iron,zinc and lead polymetallic ore deposits.It is an important polymetallic ore concentration area in Qinghai area.In addition to the southern polymetallic ore deposits in Binggou,there are also polymetallic deposits such as Hutouya and Yingqinggou.There are very similar metallogenic types and metallogenic conditions.The contact sites between the Langyashan formation and the late Triassic Elashan volcanic rock are all close to one side of the Langyashan formation.The leachate metasomatism skarn type lead-zinc polymetallic ore deposit will have fine quality and good prospecting prospects.
