新疆哈拉奇地区水系沉积物地球化学特征及找矿方向

Stream sediment geochemical characteristics and prospecting direction in Karaqi area of Xinjiang

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)严格受喀拉铁克断裂带、可牙克断裂带、塔什纳拉他乌断裂带,以及泥盆系、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4处找矿远景区,即喀拉铁克找矿远景区、布隆找矿远景区、萨喀尔得找矿远景区和猎鹰场找矿远景区,为该区下一步的找矿工作指明了方向。

For the purpose of providing basic geological information for Karaqi area, 1：50000 stream sediment survey was conducted which included geochemical characteristics and distribution regularity of 19 kinds of elements as well as delineation exceptions, and the relationship between anomalies and mineral resources was investigated. The authors analyzed the geochemical features of stream sediments as well as the relationships between elements, and found that the anomalies （high value areas） are strictly controlled by Ka- latieke fault zone, Keyake fault zone, Tashinalatawu fault zone, Devonian strata and hydrothermal activities. According to the anomalies and the ore-forming geological conditions, the authors delineated four ore-searching prospective targets, i.e., Kalatieke, Bulong, Sakaerde and Lieyingchang. The results obtained by the authors can play an important guiding role in further ore-prospecting work.
