青海省裕龙沟地区水系沉积物地球化学特征及找矿方向

Geochemical Characteristics and Ore Prospects of Yulonggou Area in QingHai Province Based on Stream Sediment Survey

摘要:

5万水系沉积物测量的基础上，对青海省共和县裕龙沟地区的地球化学特征进行了初步分析，对元素分布特征、元素的富集离散特征、元素相关性分析、异常元素组合特征进行了研究，并对工区圈定的综合异常按元素进行了排序，初步了解了工区的地球化学特征，发现Cu，Ni，Pt，Pd，Au为区内具有成矿潜力的元素。划分出裕龙沟外围、欧角北、谢日陇、勒陇、锐山5个找矿靶区，为下一步的地质找矿工作指明了方向。

Abstract:

On the basis of stream sediment survey with the scale of 1∶50000, preliminary analysis of geochemical characteristics of Yulonggou area in Gonghe county of Qinghai Province has been carried out. Elements distribution characteristics, element enrichment and discrete characteristics, element correlation analysis, abnormal element combination characteristics have been studied. Comprehensive anomalies in work area have been ranked according to elements, geochemical characteristics in work area has been preliminarily known, and some elements have been regarded as deposit potentiality, such as Cu,Ni,Pt,Pd and Au. Five target areas have been circled, they are surrounding areas of Yulonggou, Oujiaobei, Xierilong, Lelong and Ruishan. It shows directions for the deposit discovery in the future.
