摘要
洋灰洞子铜矿床地处黑龙江的东部地区,该矿是近几年来才被发现,规模为小型,分布于太平岭多金属成矿带上。文中结合实践在对该矿相关研究资料进行收集与整理,分析探讨洋灰洞子铜矿床地质特征,包括矿体形态特征以及矿石组合和结构构造、围岩蚀变、硫同位素测定、矿石爆裂温度测定等,认为该矿在形成过程中,地层与含矿岩体使其主要的成矿物质来源,具有强烈的岩浆同熔与交代成岩成矿作用,其成矿过程中分为两期,成矿温度划分为三个阶段。综合研究认为该矿为中温热液型斑岩铜矿床,和中酸性侵入岩存在较为密切的联系。
The yanghuidongzi copper deposit is located in the eastern part of Heilongjiang Province.It was discovered only in recent years.It is small in scale and distributed on the polymetallic metallogenic belt of taipingling.In this paper,combined with the practice,the related research data of the mine are collected and sorted out,and the geological characteristics of the yanghuidongzi copper deposit are analyzed and discussed,including the ore body shape characteristics,ore combination and structure structure,wall rock alteration,sulfur isotope measurement,ore burst temperature measurement,etc.It is considered that the formation process of the mine,the strata and ore-bearing rock mass make its main source of ore-forming materials have strong The metallogenic process is divided into two stages and the metallogenic temperature is divided into three stages.The comprehensive study shows that the deposit is a porphyry copper deposit of mesothermal type,which is closely related to the intermediate acid intrusive rocks.
