摘要: 甘肃省早子沟金矿位于西秦岭西段,是20世纪末通过1:20万化探扫面发现的超大型金矿,该矿床是典型的中低温岩浆热液矿床,矿体主要受断裂构造和脉岩的控制。为了解决深部找矿的问题,本文收集了矿区61个钻孔相关资料,得到了4 012个钻孔原生晕的数据。通过对原生晕数据进行相关性分析、R型聚类分析、因子分析和原生晕浓度分带特征研究,认为找矿的最佳指示元素为Au、As、Sb、Ag、Hg、W,其中与Au成矿最密切、最直接的指示元素是As和Sb;通过计算原生晕分带指数,得到了原生晕轴向分带序列(从上到下)为Au-Hg-Bi-Pb-Mo-Sb-Ag-Cu-W-Zn-Co-As,Sb和As等前缘指示元素出现在尾晕元素之后,显示深部可能存在盲矿体。基于以上研究,结合地质方面的认识,评价了矿区深部含矿性,提取了深部找矿信息。并据此构建了早子沟金矿地质-地球化学深部找矿模型,圈出了2处深部找矿靶区。

Abstract: The Zaozigou gold deposit is located at the western part of the western Qinling Mountains in Gansu Province, and it is a super-large gold deposit discovered by regional geochemistry-national reconnaissance program in the 20th century. The deposit is a typical middle-low temperature magmatic hydrothermal deposit, and the orebody is mainly controlled by fault structures and dike rocks. In order to solve the Problem of deep prospecting, we were collected related data of 61 drillings and obtained 4 012 date of drimary halo in this paper. Through the correlation analysis, R-type cluster analysis, factor analysis, and zoning characteristics of primary halo, the best combination of indicator elements for gold prospecting is Au, As, Sb, Ag, Hg, W, while the closest and most direct indicator elements to gold mineralization are As and Sb. By calculating the index of primary halos, the axial zonation of this ore deposits is as follows (from high to low):Au-Hg-Bi-Pb-Mo-Sb-Ag-Cu-W-Zn-Co-As, and the reverse zoning phenomenon of the front elements (Sb, As) shows that blind ore bodies may exist in the deep. Base on the above studies and combined with geological knowledge, the ore-bearing potential and exact prospecting information in the deep were evaluated, the geological and geochemical deep prospecting model of the Zaozigou gold deposit was constructed, and finally two deep prospecting target areas were pointed out.

Key words: primary halo, zoning sequence, deep ore prediction, Zaozigou gold deposit, Gansu Province
