摘要
摩洛哥拉希迪耶地区铅锌矿床在位于中新生代浅陆盆地边缘构造环境,受近北东东向区域断层破碎带及其次级断层破碎带控制,赋矿岩石均为下侏罗统台地相碳酸盐岩。矿体具缓倾斜的层状和陡倾脉状两种产状。金属矿物主要为方铅矿、白铅矿和菱锌矿,围岩蚀变主要有碳酸盐化、硅化等。矿床成因为MVT型铅锌矿床。
The lead-zinc deposits in the Er Rachidia region of Morocco are located in the tectonic setting of the marginal basin of the Mesozoic and Cenozoic. It is controlled by the fault zone in the NEE direction. The ore-bearing rocks are carbonate of under the Jurassic. The ore body has a gently sloping layered and steeply sloping veins. The metal minerals are mainly galena, leucite and diabase, and the surrounding rock alterations are mainly carbonate and silicification. The deposit is due to the MVT-type.
