崤山地区金银多金属矿成矿系列及成矿规律初探

Preliminary study on the metallogenic series and the metallogenic regularity of gold-silver polymetallic deposits in Xiaoshan region

崤山地区地处河南省西部,属于小秦岭-崤山-熊耳山-外方山金多金属成矿带的一部分,具有良好的成矿条件。本文在总结研究崤山地区金银多金属矿成矿地质背景、矿床地质特征的基础上,将崤山地区金银多金属矿划分为崤山式金矿床、申家窑式金矿床、银家沟式硫铁多金属矿床、中河-老里湾式银铅锌矿床4个矿床式,同时对区内金银多金属矿时空分布规律、成矿物质来源规律进行了初步探讨,在成矿系列和成矿规律研究的基础上,结合研究区最新勘查成果指出在崤山小妹河地区和龙脖水库地区仍具有较好的找矿前景。

Xiaoshan region is located in the western part of Henan province,Which is a part of the Xiaoqinling-Xiongeshan-Xiaoshan-Waifangshan gold metallogenic belt and its metallogenic conditions is good.On the basis of summarizing the geological background and geological characteristics of the gold-silver polymetallic deposits in the Xiaoshan region,this paper divides the gold-silver polymetallic deposits in Xiaoshan region into 4 types of gold deposit,Shenjiayao gold deposit,Xiaoshan gold deposit,Yinjiagou sulfur-iron polymetallic deposit and Zhonghe-Laoliwan silver-lead-zinc deposit.At the same time,the spatial and temporal distribution law of gold and silver polymetallic ore in the area and the regularity of metallogenic material source are discussed.On the basis of the study of metallogenic series and metallogenic regularity,in refer to the latest exploration results,this paper points that there is a good prospecting prospect in the Xiaomeihe area and the Longbo reservoir area.
