摘要
通过应用DMA-80测汞仪对西藏邦卓玛矿区0线剖面采集的土壤样品进行不同温度测试,对比得出热释温度区间280℃~330℃的异常曲线反映出的已知金矿体信息最佳,并选用280℃作为土壤热释汞分解温度对未知区进行找矿预测,圈定出3个有利找矿靶区,为该矿区找金矿指明方向。
The test in different temperature for soil samples at 0 line profile of Bangzhuoma mine by DMA-80 mercury analyzer have been carried out,and it is found that the anomaly curve based on analysis data from pyroelectric temperature range of 280℃ to 330℃ is best consistent with known ore body in space,then choice 280℃as pyrolysis temperature to analysis mercury in soil for prospecting prediction to unknown area.Three favorable prospecting target areas have been delineated,and it is the direction for gold exploration in future.
