Geochemical Characteristics and Ore−prospecting of Dashagou Area in East Kunlun, Xinjiang: Based on Stream Sediment Survey
-
摘要:
在1∶5万水系沉积物测量基础上，对东昆仑大沙沟一带成矿元素分布特征进行研究，获得了较为丰富的区域地球化学成果。通过对元素分布特征、元素相关性、地球化学参数特征等进行研究。结果表明，该区元素的富集与地层、构造、岩浆岩明显相关；Cu、Zn、Au、Ag、Sb、Hg富集成矿可能性较大，可作为区内主成矿元素及指示元素。本次工作共圈定37处综合异常，6处成矿远景区，5处找矿靶区，为下一步找矿工作提供了地球化学依据。
Abstract:Based on the 1∶50000 stream sediment survey, the distribution characteristics of ore-forming elements in Dashagou area, East Kunlun, and plentiful regional geochemical survey data was obtained. The author analyzed the characteristic of element distribution, geochemical features of stream sediment as well as the relationships between of elements, and found that the enrichment and depletion of elements relate to the formation, struture and magmatic rock, Cu, Zn, Au, Ag, Sb, Hg are more likely to be rich in integrated ore, which can be used as the main ore–forming element and indicator element in the area. A total of 37 composite anomalies and 6 potential ore–prospecting areas and 5 target area were delineated in this work, the results points out the direction for the prospecting work in the next stage.
