中文摘要:
      崤山地区东北部是豫西金矿化集中区之一,虽然已探明金储量远不及小秦岭和熊耳山地区,但其深部有较大的找矿潜力。研究金矿与成矿地质体的关系以及成矿构造和成矿结构面,总结成矿作用特征标志,对该区金矿深部找矿预测工作有重要意义。对区内典型金矿床“三位一体”成矿特征的总结研究表明,区内金矿化类型分为构造蚀变岩型、石英脉型和构造蚀变岩+石英脉型3种。成矿地质体为燕山期以龙卧沟、后河小岩株为地表出露标志的隐伏中酸性岩基,成矿构造系统为与崤山太华群变质核杂岩和拆离断层有关的断裂构造系统,成矿结构面主要为变质核杂岩核部的NNW、NEE和NNE向的断裂结构面。在归纳金矿成矿作用特征标志和找矿预测要素的基础上,初步建立了该区金矿的找矿预测地质模型。
英文摘要:
      The northeast of Xiaoshan is one of the important concentration area of gold mineralization in western Henan.Although proved reserves far less the gold reserves of xiaoqinling or xiongershan, but its deep part have great prospecting potential. It is of great significance to the deep prospecting prediction in this area that study the relationship between gold deposits and metallogenic geological body, as well as the metallogenic structure and metallogenic structural plane, and summarize the characteristics marks of metallogenesis.The study of the "trinity" mineralization characteristics of the typical gold deposits in the area shows that the gold mineralization types are divided into three types:structural altered rock type, quartz vein type and structural altered rock + quartz vein type. Metallogenic geological body were a insidious medium-acidic granite base of yanshan period and now it’s some small rock strains blonging to hypabyssal intrusive exposed on the earth’s surface. metallotectonic system is fracture tectonic system be related to Taihua Group metamorphic core complex and detachment fault in Xiaoshan area, metallogenic structural planes are mainly fracture planes in NNW, NEE, and NNE direction. On the basis of summarizing the characteristics of gold mineralization and the factors for prospecting prediction, a preliminary geological model for predicting gold deposits in this area is preliminaryly established.
