浅析风化壳淋积型稀土矿外生成矿过程中的影响因素

The influence factors of the exogenous metallogenic process in weathering of weathering shell are analyzed

风化壳淋积型稀土矿受内生成岩作用和外生成矿作用控制,内生成岩过程中,稀土元素在原岩中的初步富集奠定了成矿基础,大体上决定了矿床的稀土配分类型;外生成矿过程中稀土元素从原岩中释放,以离子形式在粘土矿物表面吸附成矿。外生成矿过程中稀土元素的迁移富集受多种因素影响,文章主要浅析外生成矿过程中氧化还原条件、pH值、气候条件和微生物及有机物对外生成矿作用的影响。

The weathering crust illuviation type rare earth ore by generated within the role and exogenous mineralization control, generated within the rock in the process, the initial enrichment of rare earth elements in the original rock, laid the foundation of metallogenic largely determines the distribution type ore deposit of rare earths; The rare earth elements were released from the original rock during the exogenous metallogenic process, and the ions were adsorbed into ore on the surface of clay minerals. Exogenous mineralization enrichment of rare earth elements in the process of migration is influenced by many factors, the paper mainly analyses the exogenetic ore-forming process of REDOX conditions, pH value, climate conditions, and microorganism and organic foreign mining effects.
