自然界里碱质作用广泛存在,它对成岩以及有色金属、稀有稀土金属、放射性金属等矿产的形成都有直接或间接的意义,因此,引起了地质工作者的普遍重视。笔者认为,目前广泛流行的“碱交代作用”这一术语,把不同成因的碱质作用归为一种热液交代成因模式可能不够恰当。笔者通过钨锡矿、铌钽矿和某些铀矿床碱质作用特征的初步研究,来探讨不同成
The role of alkalinity in nature is widespread. It has direct or indirect significance for diagenesis and the formation of non-ferrous metals, rare earth metals, radioactive metals and other minerals. Therefore, it has aroused widespread attention of geologists. The author believes that the widely popular “alkali metasomatism,” the term, the origin of different genesis as a hydrotreating generative model may not be appropriate. The author through the tungsten tin, niobium tantalum ore and some uranium deposits in the basic characteristics of the role of preliminary study to explore different into
