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 ,与其西邻的小秦岭相比 ,崤山金矿找矿工作始终未获重大突破 ,目前仅发现中型金矿床 1处。究其原因 ,主要是对金矿控矿构造体系研究不够深入。本文研究工作的目的是通过对崤山地区金矿控矿构造体系的实地调查、解析 ,建立金矿控矿构造体系模式 ,研究金矿矿化富集与控矿构造体系间的空间关系 ,寻求金矿找矿重大突破的方向。研究表明 ,燕山期环崤山拆离滑脱构造体系为区内金矿控矿构造体系 ,环崤山主拆离滑脱构造带为区内主要的控矿、储矿构造 。Xiaoshan and the adjacent Xiaoqinling and Xiong'ershan are all component parts of the Hua_Xionger compound terrain on the southern margin of the North China plate and therefore enjoy similar geological and gold metallogenic backgrounds. Nonetheless, relative to its west neighboring Xiaoqinling, no essential progress has been made in gold exploration in Xiaoshan except for the discovery of a medium_size gold deposit. It is held that inadequate study on the gold ore_controlling tectonic system has hindered the gold exploration in this area. The authors' work has thus aimed at the field investigation, analysis and modeling of such a system to probe into the spatial relationship between gold ore mineralization and the aforementioned system and to search for the very direction in which breakthrough may be made in gold ore exploration. The results indicate that the Yanshanian Xiaoshan detachment tectonic belt serves as the main regional ore_controlling and ore_hosting structure and is hence recognized as the gold ore_controlling tectonic system. The future gold ore exploration should therefore be focused on this belt.
