山东平邑卓家庄金矿地质特征及成矿预测

Geological characteristics and metallogenic prediction of Zhuojiazhuang gold deposit in Pingyi,Shandong Province

山东平邑卓家庄金矿是我国当前矿产资源非常丰富的隐爆角砾金矿床,虽然规模不高,但是品位很高,平均品位可达100×10^(-6),最高能够达到3000×10^(-6)以上,具有全筒式矿化的特征,位置在NW向与EW向断裂相互交汇的位置。其中的金矿矿石主要涉及到隐爆角砾岩类型、震碎角砾岩类型、破碎岩类型几种,隐爆角砾岩类型的矿石还可以分成矿浆胶结类型、热液胶结类型、岩浆胶结类型、凝灰质胶结类型几种,矿体上部分的矿石结构非常简单,但是下部分的矿石结构十分复杂,需要全面分析地质特征、准确预测成矿规律,便于精准进行金矿的开发。基于此,本文分析山东平邑卓家庄金矿地质特征,提出成矿预测的建议,旨在为增强金矿资源开发效果而提供依据。

Zhuojiazhuang gold deposit in Pingyi,Shandong Province is a cryptoexplosive breccia gold deposit with rich mineral resources in China.Although the scale is not high,the grade is very high,and the average grade can reach 100×10^(-6),up to Above 3000×10^(-6),with the characteristics of full barrel mineralization,which is located at the intersection of NW and EW faults.Among them,the gold ore mainly involves cryptoexplosive breccia type,earthquake broken breccia type and broken rock type.The cryptoexplosive breccia type ore can also be divided into pulp cementation type,hydrothermal cementation type,magmatic cementation type and tuffaceous cementation type.The ore structure of the upper part of the ore body is very simple,but the ore structure of the lower part is very complex.It is necessary to comprehensively analyze the geological characteristics and accurately predict the metallogenic law,It is convenient for accurate gold development.Based on this,this paper analyzes the geological characteristics of Zhuojiazhuang gold deposit in Pingyi,Shandong Province,and puts forward some suggestions for metallogenic prediction,in order to provide a basis for enhancing the development effect of gold resources.
