| 摘 要： | 邹平王家庄铜矿是山东重要的斑岩型铜(钼)矿床,产于中生代陆相火山岩盆地中,矿石物质组分复杂,以富含硫砷铜矿为特征,并伴有金矿化。通过显微镜下详细的矿石物质组分研究,结合电子探针微区分析、扫描电镜及能谱分析等测试技术,在矿石中新发现了铀矿物及铂族元素矿物(PGM)。测试结果表明,铀矿物为铜砷铀云母,与孔雀石等铜的氧化物一起分布于矿体氧化带中;PGM为碲钯矿、黄碲铋钯矿等钯的碲化物,包裹于针硫铋铅矿中,粒度较小,成分复杂。结合矿床地球化学资料,讨论了成矿物质来源及铂族元素(PGE)和U的迁移富集机制。认为成矿物质来源于地幔,矿床成因与地幔上隆、地壳减薄及深断裂活动有关。岩浆期后产生的富含金属络合物的高盐度热液对PGE和U的迁移富集起重要作用,隐爆作用造成的剧烈温压降低及气体散失、络合物分解是矿质聚集沉淀的重要条件。

| Abstract: | The Wangjiazhuang copper deposit in Zouping is an important porphyry copper and molybdenum deposit in Shandong Province. It is located in Mesozoic continental volcanic basin in western Shandong. Recently, through the detailed observation under microscope, SEM and EPMA analysis, the uranium mineral and platinum group minerals (PGM) were descovered for the first time in cryptoexplosive breccia type and quartz vein type ores. They include palladium mineral A(AgPdTe2), kotulskitePd(Te, Bi)], merenskyite (PdTe2), and zeuneriteCu(UO2)2(AsO4)2·(10~16)H2O]. PGM generally is wrapped in aikinite with complicated composition and smaller particle size. Zeunerite is accompanied by azurite, covelline and other copper oxides in the oxidation zone. Combined with geochemical data, the authors investigated the ore-forming material sources and mechanism of migration and concentration of platinum group elements (PGE) and U, and concluded that the ore-forming materials were derived from the mantle and the formation of this deposit was related to mantle uplift, crust thinning and deep fault activity. In addition, the migration of PGE and U might have been associated with high salinity hydrothermal solution, and the precipitation conditions should be the gas loss and decomposition of the complex from severe changes of temperature and pressure caused by cryptoexplosive. |
