摘　　要：以崤山矿田控矿构造为研究对象,阐述了崤山矿田西北部和东南部典型矿床控矿构造类型、特征、力学性质及矿化构造特征。通过综合分析,认为崤山西北部的半宽—葫芦峪—申家窑一带为韧性剪切带控矿,东南部的大方山—宽平—寺家沟一带为脆性断裂控矿;崤山变质核杂岩地体在成矿后发生了整体性差异隆升,西北部相对翘起,东南部相对下落。在东南部脆性控矿断裂系统之下,应存在类似于西北部那样的韧性剪切带容矿构造系统。该研究为崤山矿田西南部的深部成矿预测、找矿方向提供了思路。Taking the ore controlling structure of Xiaoshan ore field as the research object,the ore controlling tectonic types,characteristics,mechanical properties and mineralization characteristics of the typical ore deposits in the northwest and southeast of Xiaoshan ore field are described.By comprehensive analysis,it is figured out that the Bankuan-Huluyv-Shenjiayao area in the northwest of the mountain is controlled by ductile shear zone,the Dafangshan-Kuanping-Sijiagou area in the southeast is controlled by brittle fracture.Xiaoshan metamorphic core complex has undergone genomically differential uplift after mineralization,tipping up in the northwest and dropping in the southeast.Under the brittle ore-controlling fault system in the southeast,there should be a ductile shear zone bearing tectonic system similar to that in the northwest.This study has provided a guideline for the deep ore prospecting prediction and prospecting orientation in the southwest of Xiaoshan ore field.
