西昆仑瓦仍孜拉地区水系沉积物地球化学异常特征及找矿预测

Geochemical anomaly characteristics and prospecting prediction of stream sediments in washangzila area,West Kunlun

西昆仑塔什库尔干地区分布有一系列沉积变质型铁矿,在土壤地球化学测量效果不佳和磁法未覆盖的瓦仍孜拉地区开展了1:5万水系沉积物测量。通过对区内元素地球化学特征分析总结,圈定了单元素异常和综合异常,探讨了1:5万水系沉积物地球化学测量工作在瓦仍孜拉地区的应用前景。圈定了三个找矿靶区。玛纳苏里铁多金属元素找矿靶区(B类);希其里阿镉、铬、锌、水晶找矿靶区(C类);吐尔得库勒钼、铋、钨、硫磺找矿靶区(C类)。

A series of sedimentary metamorphic iron ores are distributed in Tashkurgan area of West Kunlun.1:50000 stream sediment survey has been carried out in wasunzila area where the effect of soil geochemical survey is not good and not covered by magnetic method.Based on the analysis and summary of the element geochemical characteristics in the area,the single element anomaly and comprehensive anomaly are delineated,and the application prospect of 1:50000 stream sediment geochemical survey in wahuanzila area is discussed.Three prospecting targets were delineated.Manasuli iron polymetallic element prospecting target area(class B);Xiqiria cadmium,chromium,zinc and crystal prospecting target area(Class C);Tuldekule molybdenum,bismuth,tungsten and sulfur prospecting target area(Class C).
