摘要
崤山金矿外围位于豫西金矿化集中区之一的崤山地区,在野外观察的基础上,对崤山外围金矿开展矿床地质特征、矿石类型及矿床成因等方面的研究.认为矿床类型为蚀变岩型,矿床明显受构造控制;成矿流体以岩浆水为主,成矿过程中可能混入大气降水;成矿物质来源与燕山期花岗岩体有关.同时对地层、构造、岩浆岩等方面进行矿床成矿条件分析,总结了区内金矿成矿标志,以期对该区金矿找矿预测工作提供一些参考.
Abstract
Periphery gold deposit of Xiaoshan is located in xiaoshan district,one of the gold mineralization areas in western Henan province.We have studied the geological characteristics,ore types and ore genesis of the deposits based on field observation.It is concluded that the deposit type is alteration rock type.The deposit is obviously controlled by fracture.The ore-forming fluid is mainly magmatic water,which may be mixed with atmospheric precipitation during the ore-forming process.The source of ore-forming material is related to magmatic activity.We also summed up the gold mineralization markers in the area through the strata,structure,magmatite and other aspects of ore deposit metallogenic conditions analysis.It will play a certain guiding role in the gold prospecting prediction work in this area.
