吉林省红旗岭矿区7号岩体群地质特征及对地质找矿的指导意义

红旗岭矿区的南东部存在7、32、33号三个岩体,一般统称为7号岩体群。7号岩体是矿区发现含铜、镍矿最大的岩体,32与33号岩体分布在7号岩体的北西部。通过对这三个岩体的地质特征进行分析,利用3Dmine软件建模技术,对三个岩体、岩相、矿体建立三维模型。对模型进行观察、分析,结合成岩成矿地质理论,发现三个岩体是由来自7号岩体的南东部深部岩浆源生成的,岩浆由7号岩体的南东部深部向北西方向侵入,地质历史上三个岩体是一个大岩体,只是经过长期的风化剥蚀和地质构造改造形成目前的3个岩体,显示7号岩体的南东部深部具有找矿潜力。

Geological characteristics and its guiding significance for geological prospecting of No.7 rock-mass group in Hongqiling mining area,Jilin Province

There are three rock mass of No.7, No.32 and No. 33 in the east-south of the Hongqiling mining area, it is generally referred to as the No.7 rock mass group. The N o. 7 rock mass is the largest rock mass found to contain copper and nickel in the mining area. There are also 32 and 33 rock masses in the west-north of No.7 rock mass. Through the analysis of the geological characteristics of these three rock masses. Modeling technology using 3Dmine software, Threedimensional models were established for three rock masses, lithofacies and ore bodies. Observe and analyze the models,Combining diagenesis Metallogenic geology theory, Three rock mass were found to have been generated by deep magma sources in the east-south from No.7 rock mass, The magma invades from the deep east-south of No.7 rock mass to the west-north. Three rock masses in geological history was a large rock mass. Only after a long period of weathering and denudation and geological structure transformation to form the current 3 rock masses. It shows that the deep east-south of No. 7 rock mass has prospecting potential.
