| 摘 要： | 滇西北北衙金矿床是与富碱斑岩有关的矽卡岩-斑岩型金多金属矿床,矿床的分布与接触带构造及斑岩体产出的断裂构造息息相关,这为构造地球化学勘查技术应用奠定了基础。笔者通过R型聚类分析和因子分析得到2个元素组合:Au-Ag-Fe-Cu-Sb-Hg-Sn-Pb-Co-Mo;Zn-Pb,绘制元素组合构造地球化学异常图。据图可以推测成矿流体的运移方向、矿体产状,同时认为笔架山矿段成矿规模虽较万硐山矿段小,但是具有较大勘查潜力。

| Abstract: | Located in northwest Yunnan, the Beiya gold deposit is a skarn porphyry type gold polymetallic deposit with rich alkali. The distribution of orebodies is related to structure and porphyry, which constitutes the basis for the application of the tectonogeochemical method. Through R type cluster analysis and factor analysis, the authors recognized two combinations of elements. One is Au-Ag-Fe-Cu-Sb-Hg-Sn-Pb-Co-Mo, and the othor is Zn-Pb. Then the authors used them to draw a tectono-geochemical map, which included the combination of elements and anomalies. With the map, the authors detected the migration direction of the ore-forming fluid and the location of the orebody. It is held that the Bijia Mountain has a relatively good exploration potential. |
