| 中文摘要: |
| 豫西崤山地区经历了长期而复杂的地质发展演化,从新太古代到中生代不断活动,奠定了该区的基本构造格架。以成矿的区域地质背景为依据,根据控矿地质条件和矿石特征等要素,把区内金矿床(点)划分为构造蚀变岩型、石英脉型、斑岩—夕卡岩型3种矿床类型。文章阐述了各类型矿床的地质特征,归纳总结了该区成矿地质规律,构建了崤山矿集区金矿成矿模式,即矿源层、构造、岩浆热动力作用和有利的容矿空间“三位一体”的成矿模式,指出了不同类型矿床找矿的主攻方向。 |
| 英文摘要: |
| The Xiaoshan region, western Henan Province experienced a long and complicated continuous geological evolution from the Neoarchean period to the Mesozoic period which laid the basic regional tectonic framework. Based on the geological metallogenic background, the gold deposits (occurrences) in the Xiaoshan region are classified into three ore deposit types, i.e., structural alteration rock type, quartz vein type and mixed porphyry - skarn type according to the geological conditions and ore characteristics. This paper describes the geological characteristics of those types of gold deposits (occurrences) in detail, summarizes the metallogenic rules and constructs the metallogenic model of the Xiaoshan gold deposits, i.e., “Trinity” metallogenic model consisting of the ore source layer, structure control and magmatic thermal dynamic effect and the favorable mineralization deposition space, finally proposes the main prospecting targets for different types of gold deposits. |
