本文選題：SHMS類(lèi)礦床　切入點(diǎn)：萊茵海西期地體　出處：《地質(zhì)通報(bào)》2017年08期

【摘要】：拉梅爾斯貝格礦床是中歐華力西期最重要的SHMS(以沉積巖為容礦圍巖的塊狀硫化物)類(lèi)礦床之一,位于萊茵海西期地體的上哈茨地塊。該礦床形成于泥盆紀(jì),礦體賦存于艾菲爾階的威森巴赫頁(yè)巖中,經(jīng)華力西造山運(yùn)動(dòng)發(fā)生了強(qiáng)烈的變形。主要有新礦體、老礦體和富含重晶石的灰色礦體,主要硫化物礦物為黃鐵礦、閃鋅礦、方鉛礦和黃銅礦。硫同位素?cái)?shù)據(jù)顯示,拉梅爾斯貝格礦床有2個(gè)硫源,一個(gè)是熱液成因;一個(gè)是生物成因,來(lái)自細(xì)菌還原的海水中的硫酸鹽。鉛同位素說(shuō)明,它的鉛主要來(lái)自均勻的地殼。與其他SHMS類(lèi)礦床相比,拉梅爾斯貝格礦床明顯富銅。
[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.
