吉林集安铅锌矿床是我国最早报导的少数几个典型低温铅锌矿床之一。矿化具有多期次特点 ,富矿体都是多期次矿化叠加的产物。根据矿化先后和矿物生成顺序将矿化分为五个阶段 :①石英 黄铁矿矿化阶段 ;②重晶石 闪锌矿矿化阶段 ;③石英 方铅矿矿化阶段 ;④石英 黄铁矿矿化阶段 ;⑤碳酸盐 氧化矿物矿化阶段。用均一法和爆裂法测得石英、重晶石、闪锌矿包裹体成矿温度变化在 1 1 0℃～ 1 97℃之间。矿床中除含铅锌矿外 ,还有微量的Pt和Pd,并普遍含分散元素Cd、Ga、Tl、In、Se、Ge、Te,其中以Cd含量最高 ,闪锌矿中Cd含量最高可达 71 5 5× 1 0 6。分散元素主要呈类质同象形式赋存在各种矿物之中 ,未发现独立矿物。通过矿床地质和硫铅同位素研究表明该铅锌矿床属低温沉积 改造型层控矿床。
Jilin Ji’an lead-zinc deposit is one of the few typical low-temperature lead-zinc deposits reported in China. Mineralization has multi-stage characteristics, rich ore bodies are multi-stage mineralization superposition of the product. The mineralization is divided into five stages according to the sequence of mineralization and the sequence of mineralization: ① quartz pyrite mineralization stage; ② barite sphalerite mineralization stage; ③ quartz galena mineralization stage; ④ quartz yellow iron Mineralization stage; ⑤ carbonate mineralization mineralization stage. The ore-forming temperature of quartz, barite and sphalerite inclusions measured by the homogeneity method and the burst method varied from 110 ℃ to 1 97 ℃. In addition to lead-zinc ore deposits, there are trace amounts of Pt and Pd, and generally contain dispersed elements Cd, Ga, Tl, In, Se, Ge and Te with the highest Cd content and the highest Cd content in sphalerite Up to 71 5 5 × 10 6. Dispersing elements were mainly in the form of the same type of minerals found in various minerals, no independent minerals were found. Through the study of deposit geology and sulfur and lead isotopes, the lead-zinc deposit is a low-temperature sedimentary-modified stratabound deposit.
