摘要
湘东北某地硅化带、石英脉极为发育,铅锌矿化广泛,但分布零散。为达找矿之目的,根据1:50000土壤化探资料,用块段平均法计算,编绘Pb、Zn、Cu地球化学异常图。圈定的异常大多与矿脉吻合,再根据具体地质条件,预测找矿有利地段。
Silicified zone and quartz vein are extremely developed in a certain area in Northeastern Hunan, with extensive occurrence of lead-zinc mineralizations but scattered fragmentarily. In order to find mineral deposit, based on 1:50000 scale geochemical soil survey data,Pb, Zn and Cu geochemical anomaly maps are drown up using data calculated by block average method. Most of the anomalies contoured coincides with known veins. With consideration of the concrete geological condition,they can be used to predict favourite prospecting target areas.
