摘    要:小秦岭金矿为产于绿岩中的脉状金矿床,受韧脆性剪切带控制。文章根据危机矿山项目在小秦岭地区的深部探矿资料,结合浅部勘探资料,通过研究认为:剪切带的规模与分布密度与金矿的成矿关系密切;剪切带的产状变化控制矿体的富集部位。剪切带演化的不同期次与不同成矿阶段相对应。总结控矿模式为“一街五巷三层楼”模式。

关 键 词:金矿床  剪切带  控矿规律  控矿模式  小秦岭

Abstract:Xiaoqinling gold ore deposit is a veined-type deposit, controlled by brittle ductile shear zone, in the greenstone belts. Based on the deep prospecting reports about Xiaoqinling area of the crisis mine project, and the superficial exploration material, it is proposed that the scale and distribution density of the shear zone is closely relative with the ore-formation. The occurrence pattern changes of shear zone controls the enrichment area of the orebody. Different evolution stages of the shear zone are corresponded to different metallogenic steps. The ore-controlling model is a pattern of Yijie-Wuxiang-Sancenglou.
Keywords:gold deposit  shear zone  ore-controlling regularity  ore-controlling model  Xiaoqinling
