| 中文摘要: |
| 西藏仁多岗地区处于冈底斯—念青唐古拉构造带中新生代成矿域内，该构造带包含铜钼金铁成矿构造单元及铅锌银铜多金属成矿亚带，找矿前景较好，通过 1∶5万水系沉积物测量，结合地质背景分析，根据元素之间的相关性、主要指示矿种元素种类和空间分布特征，将仁多岗地区水系沉积物元素异常组合分为 3类:以 Au、Ag元素为主的综合异常，以 Cu、Pb、Zn元素为主的综合异常和以 W、Mo、Sn、Bi元素为主的综合异常。通过区内综合异常的圈定和异常查证，在研究区新发现了嘎布拉等多处矿床(点)，找矿效果显著，为该区域进一步找矿指明了方向，同时也显示了研究区较好的找矿潜力。 |
| 英文摘要: |
| Renduogang area could be divided into three types of stream sediment element anomaly combina. tions:comprehensive anomalies dominated by Au and Ag elements，comprehensive anomalies dominated by Cu， Pb，Zn elements，and comprehensive anomalies dominated by W，Mo，Sn，Bi elements through a 1∶50000 stream sediment survey，combined with geological background analysis，and based on element correlations，spatial distribution characteristics， and major indicator element types. Through the delineation and verification ofcomprehensive anomalies within the study area，several mineral deposits(spots) such as Gabla has been discovered，with significant exploration results. This has indicated the direction for further exploration in theregion and also demonstrated the considerable mineral exploration potential in the study area. The Rendogang areain Tibet is located in the Gangdise-Nianqing Tanggula Mesozoic-Cenozoic Cu Mo Au Fe metallogenic belt，and the Nianqing Tanggula Mesozoic-Cenozoic Pb Zn Ag Cu metallogenic belt，and has a good prospecting prospect. |
