摘要
在内蒙古克什克腾旗——白音查干地区,运用土壤地球化学测量方法发现了诸多以银锡为主的成矿元素异常带及找矿靶区,找矿潜力较大。通过1∶5万土壤地球化学测量工作,圈出了成矿元素异常靶区3处,经过1∶1万土壤地球化学测量,进一步缩小了找矿靶区,确定了成矿有利地段12处。经过地质填图及地表工程揭露,发现银、锡、铅锌矿(化)蚀变带20余条,其中,达到边界及工业品位的矿体5条,充分说明了土壤地球化学测量方法在半干旱风成砂覆盖的草原丘陵地区具有良好的找矿效果。
in the Inner Mongolia Hexigten Banner Baiyinchagan prospecting target areas with many in silver tin is main mineral area, were found by geochemical soil survey and element anomaly, prospecting potential. As in the Baiyinchagan area by 1：5 million soil geochemical survey, circle the metallogenic element anomaly target area 3, after 1：1 million soil geochemical survey, narrowed further ore prospecting target areas, determine the mineralization favorable area 12. Through geological mapping and surface engineering exposure, found in silver, tin, lead zinc ore （mineralized） alteration zone of more than 20, among them, reaching orebody boundary and industrial grade 5, fully said showed that soil geochemical survey method in semi arid aeolian sand covered grassland in hilly area has a good prospecting effect.
