摘要
崤山与其毗邻的小秦岭、熊耳山同属华北地块南缘华熊复合地体的一部分,金矿成矿条件相似.但是,与其西邻的小秦岭和东南的熊耳山地区相比,崤山金矿找矿工作始终未获重大突破.为加强对崤山地区成矿地质规律和容矿构造研究,笔者收集了大量崤山地区区域地质和研究成果资料,在分析研究已有地质成果的基础上,对崤山地区申家窑等十余个矿床(点)和张家河等4处燕山期中酸性岩体进行了实地调查和分析测试,并借助于崤山地区1:5万重力测量和1:5万磁法测量成果,阐述了崤山地区地质特征,指出了不同方向层间剥离构造、NW向陡倾斜断裂构造、NE向陡倾斜断裂构造等3个方向为崤山地区金(银)矿床的主要容矿构造,分析了成矿规律.
Abstract
Same as Xiaoqinling and Xiong'ershan in its adjoining area,Xiaoshan also belongs to Huaxiong composite terrane at the southern margin of North China block,and has the similar conditions for gold mineralization.However,Xiaoshan gold deposit hasn't achieved major breakthrough in its prospecting works like it did in Xiaoqinling on its west and in Xiong'ershan area on its south east.The author collected a large amount of documents related to regional geology and research results in Xiaoshan area in order to learn more about the metallogenic regularity and ore-host structure in Xiaoshan area.Based on the analysis of the existing geological results,this paper conducted field survey and analytic test in Xiaoshan area on more than ten deposits (mineral occurrences) in Shenjiayao and four Yanshanian acidic rock bodies in Zhangjiahe.With the help of the results of 1 ∶ 50 000 gravity survey and 1 ∶ 50 000 magnetic survey in Xiaoshan area,the author elaborated on the geological characteristics and analyzed the metallogenic regularity.It indicates that the main orehost structures of the gold (silver) deposit in Xiaoshan area include the interlayer fissile structure in various directions,NW-trending high-dipping fractures and NE-trending high-dipping fractures.
