| 摘 要： | 矿床原生晕地球化学轴向分带是深部矿体预测的重要依据。研究表明:大湖金矿具有多期多阶段叠加成矿的特点,通过对大湖矿区F5构造带内的17、19、22号矿体及其蚀变围岩中Au、Ag、Co、Cu、Mn、Mo、Ni和Pb等18种元素含量进行相关分析和聚类分析,着重探讨矿体的原生晕特征,并以小秦岭金矿田构造叠加晕理想模型为参照,解释矿体的原生晕特征,进而开展成矿预测,以期为小秦岭金矿田其他矿区的深部找矿勘探提供参考。

| Abstract: | The deposit geochemical primary halo axial zonation is an important basis to predict of deep ore body. Gold mineralization is superimposed with characteristics of multi-phase and multi-stage in Dahu gold deposit. Anomalies combination of geochemical elements in different elevation is different of location of orebody.This paper focuses on content of Au,Ag,Co,Cu,Mn,Mo,Ni,Pb and other 18 kinds of elements in No.17,19 and 22 orebody in the F5 structural zone in Dahu gold mine and altered rocks,we do the correlation analysis and poly class analysis,and focuses on the characteristics of their primary halo.We takes the Xiaoqinling gold field structural superimposed halo ideal model as a reference to explain the characteristics of the orebody primary halos,it is believed that the elongation of No.19 orebody is not very long.To write this paper,we except to provide a reference for deep gold mine prospecting and exploration of other fields in Xiaoqinling. |
