摘要:
大兴安岭成矿带是我国重要的有色金属成矿带之一,库伦迪铅锌矿床是近年来在该带北段中发现的中型矿床之一。本文在系统的野外地质调查的基础上,对该矿床的矿石开展详细的矿石特征研究。结果表明:库伦迪矿床矿石可划分为锌铅矿石、锌铅铜矿石、铜锌矿石和铅矿石等4种类型; 各矿石类型矿物共生组合分析表明,按成因该矿床矿石结构可分为结晶结构、交代结构、固溶体分离结构和压碎结构; 矿石构造以细脉状构造、浸染状构造、块状构造和团块状构造为主,条带状构造次之。综合矿物学特征,将成矿期次划分为两期:第一成矿期为闪锌矿—黄铜矿成矿期,并划分为辉钼矿—磁铁矿成矿阶段、黄铁矿—闪锌矿成矿阶段、闪锌矿—黄铜矿成矿阶段; 第二成矿期为方铅矿成矿期,主要有方铅矿、黄铁矿、闪锌矿、黄铜矿等。
Abstract:
The Da Hinggan Mountains is one of the most important polymetallic metallogenicbelts in China, where the Kulundi lead-zinc deposit was discovered in recent years. This paper, in combination with field investigations, carried out a detailed study on the characteristics of ore minerals in the Kulundi deposit. The result shows that the ores in the Kulundi deposit can be divided into four types, zinc-lead ore, zinc-lead-copper ore, lead-copper ore and lead ore, respectively. The ore textures can be classified as crystalline texture, metasomatic texture, solid solution separation textrue and crush texture. The primary ore structures are veinlet, dissemination, block and mass, with banded structure as secondary. Comprehensive mineralogical characteristics indicate there are two mineralizationstages. The first is sphalerite- chalcopyrite stage, which can be further divided into three sub-stages of molybdenite-magnetite, pyrite-sphalerite and sphalerite- chalcopyrite, respectively, and the second is galena stage, which is comprised of galena, sphalerite, pyrite and chalcopyrite, etc.
