青海省都兰县阿拉克湖地区水系沉积物地球化学特征及找矿方向

分析了区内的水系沉积物地球化学参数特征及其元素的相关性,认为元素(地球化学)异常(高值区)严格受东昆中断裂带、东昆南断裂带、布青山南坡乌断裂带,以及阿尼玛卿蛇绿岩带和东昆中蛇绿岩带,古-中元古代地层、岩体接触带、热液活动、脉岩等因素联合控制。根据异常特征与成矿地质条件,圈定了找矿远景区5个,且为该区下一步的找矿工作指明了方向。

Geochemical characteristics of the stream sediment and prospecting direction in Alake lake area,Dulan county in Qinghai province

The characteristics of geochemical parameters and correlation of elements of the stream sediment are studied in this article.Based on the analysis,it is believed that the element anomalies are controlled by combined factors ,such as central fault zone of east Kunlun mountains,south fault zone of east Kunlun mountains,Nanpowu fault zone of Buqing mountain,Animaji ophiolite belt and central ophiolite belt of east Kunlun mountains,paleoproterozoic-mesoproterozoic strata,contact zone,hydrothermal activity and dyke rock.Five perspective zones for exploration are confirmed by the anomaly features and geological settings, which will help to guide the further prospecting work in this area for the future.
