| 摘 要： | 通过对黄吉沟地区进行土壤地球化学测量,分别运用传统统计法和分形—求和法对Au、Cu、Bi、W的异常下限进行计算,并圈定了单元素异常图;确定了测区内的构造破碎带为Au、Cu有利富集区,而Bi、W与花岗岩密切相关。同时,在小范围尺度下,统计法在寻求主攻矿体时的作用明显,而分形法在矿体外围寻求找矿突破时实用性较强。

| Abstract: | The anomaly thresholds for Au, Cu, Bi, W elements are calculated by means of statistic method and fractal-summation method, and single element anomalies for Au, Cu, Bi, W are delineated on the basis of pedogeochemical survey data. The results indicate that enrichment in Au and Cu is related to fractured zone and Bi-W mineralization is related to granite rock mass. |
