通过对吉林省永吉县乱木桥沟钼矿床的地质特征研究以确定其成因类型.乱木桥沟钼矿床位于燕山期大黑山复式岩体中的前撮落不等粒花岗闪长岩内;矿石类型为蚀变中细粒花岗闪长岩型矿石,厚度变化系数平均84.72%,品位变化系数191.21%;矿石的结构主要为半自形粒状结构、碎裂结构等.矿石的构造主要有浸染状构造、网脉状构造、团块状构造.矿床位于大黑山钼矿床外围,二者部分矿体相连,类比认为本矿床浅成中温斑岩型钼矿床.
Genesis and geological features of the Luanmuqiaogou molybdenum deposits in Yongji County,Jilin Province
The geological features of the Luanmuqiaogou molybdenum deposit in Yongji County,Jilin Province were studied to determine its genesis type.The Luanmuqiaogou molybdenum deposit is located within the Qiancuoluo unequal grain granodiorite of the Daheishan composite pluton in the Yanshan Period.The ore type is metamorphosed medium-grained granodiorite type,with thickness variation coefficient 84.72%,and grade variation coefficient 191.21%.The structure of the ore mainly consists of subhedral grain structure and fragmented structure.The texture of the ore mainly consists of disseminated texture,vein-like texture,and lump-like texture.The deposit is located in the periphery of the Daheishan molybdenum deposit,and the two de-posits have partially connected ore bodies.It is inferred that the deposit is a shallow-formed intermediate-temperature porphyry molybdenum deposit.
