炭质泥状岩是一种特殊的岩石,过去曾称为富炭泥岩,产于“江南台隆”边缘的早寒武世含铀层炭质板岩中,具颜色黑、体重轻、孔隙大、成分杂及软泥状等特点,与铀矿化关系密切。按其成因,可分为沉积成岩型、构造淋滤型、风化型三种。通过在该区七个矿床(点)的粘土矿物的X光衍射分析,结合透射电镜和差热分析研究表明,不同的岩石类型,有着各自的粘土矿物组合,可分为四种组合类型(表1),即A类型为伊利石、斜绿泥石、高岭石、埃洛石的组合;B类型为高岭石、纤磷钙铝石的组合;C类型为斜绿泥石、伊利石、
Carbonaceous muddy rock is a special type of rock that was previously known as a carbonaceous mudstone. It was produced in the early Cambrian uranium-bearing carbonaceous slate at the margin of “Jiangnan-Tai Long”, with dark-colored, light-weight, porous Large, miscellaneous composition and lime mud-like features, and uranium mineralization are closely related. According to its causes, it can be divided into sedimentary diagenesis type, leaching type and weathering type. X-ray diffraction analysis of clay minerals in seven deposits (points) in the area combined with TEM and DTA shows that different rock types have their own combination of clay minerals and can be divided into four types of combinations 1), that is, the combination of type A is illite, plagioclase, kaolinite, and halloysite; the type B is a combination of kaolinite and pyroite; the type C is metakaolin, illite ,
