【摘要】：拉梅尔斯贝格矿床是中欧华力西期最重要的SHMS(以沉积岩为容矿围岩的块状硫化物)类矿床之一,位于莱茵海西期地体的上哈茨地块。该矿床形成于泥盆纪,矿体赋存于艾菲尔阶的威森巴赫页岩中,经华力西造山运动发生了强烈的变形。主要有新矿体、老矿体和富含重晶石的灰色矿体,主要硫化物矿物为黄铁矿、闪锌矿、方铅矿和黄铜矿。硫同位素数据显示,拉梅尔斯贝格矿床有2个硫源,一个是热液成因;一个是生物成因,来自细菌还原的海水中的硫酸盐。铅同位素说明,它的铅主要来自均匀的地壳。与其他SHMS类矿床相比,拉梅尔斯贝格矿床明显富铜。
[Abstract]:The Ramelsberg deposit is one of the most important SHMS deposits (massive sulphides with sedimentary rocks as the host rock) in Central Europe and is located in the Upper Hats block of the Rhine Hercynian terrane. The deposit was formed in the Devonian. The orebody occurred in the Weisenbach shale of the Eiffel stage and was strongly deformed by the Wallis-orogenic movement. There are mainly new orebodies, old orebodies and gray orebodies rich in barites, and the main sulfide minerals are pyrite and sphalerite. Galena and chalcopyrite. Sulfur isotopic data show that there are two sulfur sources in the Ramelsberg deposit, one is hydrothermal origin, the other is biogenetic, from sulfate in bacterially reduced seawater. Its lead mainly comes from the uniform crust. Compared with other SHMS deposits, the Ramelsberg deposit is obviously rich in copper.
