摘要
藏南普容朗至界米拉一带金、锑矿位于雅鲁藏布江—大喜马拉雅成矿带之洛扎—隆子铅锌多金属矿找矿远景区东段,成矿地质条件优异。本文在综合分析1︰5万水系沉积物测量、中梯激电测量的成果圈定异常范围区的基础上,进行矿调路线的踏勘和查证,结合槽探、浅井山地工程等地质工作。得出了以下认识:①确认新发现普容朗、汤多、余对、布邛浦、日阿拉、卡拉山口、里普线、公垅卓戈等多个锑矿化点或异常带;②根据单元素的套合情况圈定综合异常35处,并对异常区进行踏勘和查证,先后发现锑金矿(化)点多处。井等工程验证,新发现多个金、锑矿点,展现了普容朗至界米拉一带金、锑矿良好找矿效果。③提出了朗县普容朗锑矿、区民那锑矿、余对锑矿、界米拉金铅多金属矿、登琼金矿5个找矿潜力区,显示了普容朗至界米拉一带金、锑矿巨大的找矿潜力,同时为下一步地质探矿提供了重要方向。
The gold and antimony deposits in Puronglang-Jiemila area of South Tibet are located in the east part of the Luozha-Longzi lead-zinc polymetallic prospecting area in the Yarlung Zangbo River-Great Himalayan metallogenic belt,with the excellent metallogenic geological condition.Based on the comprehensive analysis of the result of 150000 stream sedimentary survey and intermediate gradient induced polarization survey,this paper has delineated the anomaly range area,the geological survey and the reconnaissance and verification are carried out,combined with the geological engineering work of trench and shallow well.The following understandings are obtained.(1)There are newly discovered and confirmed for Puronglang,Tangduo,Yudui,Buqiongpu,Riala,Kala Pass,Lipu Line,Gonglong Zhuoge and other antimony mineralization points and anomaly zones.(2)According to the combination of single element,35 comprehensive anomalies are delineated,and the anomaly areas are surveyed and verified.(3)Five prospecting potential areas are pointed out,including Puronglang antimony mining area,Yudui antimony mining area,Jiemila gold-lead polymetallic mining area and Dengqiong gold mining area in Langxian County.It is shown that there is a great prospecting potential of gold and antimony deposit in Puronglang-Jiemila area.It provides an important direction for the next geological prospecting work.
