为研究二棚甸子-宽甸万宝一带铜钼矿成矿的地质特征,对这一成矿带铜钼矿所处的区域地质背景,矿区、矿体地质特征等进行论述,分析总结矿体的成矿条件,探究岩浆活动、构造运动及围岩蚀变与铜钼矿体成因之间的关系.结果表明:铜矿体多产于岩体内部或接触带附近,钼矿体主要赋存在花岗闪长岩岩体内,刘家沟、昌邑沟钼矿体赋存于花岗斑岩或石英斑岩围岩,滚立岔则是一条燕山期侵入的花岗闪长岩与古生界地层所形成的含铜多金属矽卡岩带;断裂构造多具控岩控矿作用,为成矿提供元素的运移通道,断裂交汇处是储矿的有利部位;围岩总体上具有硅化、钾化、伊利石—水云母化、黄铁绢英岩化等.
In order to study the geological characteristics of the mineralization of the copper-molybdenum deposit in Wandengzi-Kuandian Wanbao area, this paper discusses the regional geological background, the geological features of the ore area and the orebody in the copper-molybdenum mine, and analyzes the ore body The relationship between magmatic activity, tectonic movement and wall rock alteration and genesis of copper-molybdenum ore body is discussed.The results show that the copper ore body is prolific in the inner part of the rock mass or near the contact zone, In the diorite porphyry, the molybdenum ore bodies of Liujiagou and Changyigou occur in the granite porphyry or quartz porphyry wall rocks, while the rolleicha is a granodiorite intrusive granitic diorite and paleontology Copper-bearing polymetallic skarn zone formed by the boundary strata. The fault structure is mostly controlled by the rock-control ore deposit, which provides element migration pathways for ore-forming. The fault junction is a favorable site for ore storage. The wall rock generally has silicification , Potassium, illite - mica, yellow sericite and other rocks.
