| 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。金成矿成晕具有多期多阶段叠加特点,本文通过对大湖矿区矿体原生晕元素进行统计分析和空间分布特征研究,总结了大湖矿区金矿体的原生晕理想模型:即前缘晕元素组合为As、Sb,近矿晕元素组合为Bi、Au、Ag、Mo、Pb、Cu,矿尾晕元素组合为Mn、Zn、V、Co、Ni。根据原生晕特征进行成矿预测,经过工程验证,在8线发现4层金矿体,在4线发现1层金矿体,取得了较好的找矿效果,为小秦岭金矿田其他矿区的深部找矿勘探提供了参考。

| Abstract: | This paper focuses on the characteristics of primary halo in Dahu gold deposit. The results show that the combination of front halo elements are As and Sb,the near ore halo elements combination are Bi, Au, Ag,Mo, Pb and Cu, the ore tail halo elements are Mn, Zn, V, Co and Ni; According to the characteristics of primary halos ,we take a metallogenic prognosis,and get a prospecting results. |
