摘要
近年来稀土矿的勘查成功是与成矿理论的发展相互促进的。内生稀土矿床中最重要的是与碱性岩和碳酸岩有关的矿床，大多分布在板块边缘的深断裂内或其附近，呈由多种岩石组成的复合岩体产出。外生稀土矿床中最重要的是海滨砂矿。由于砂矿中的稀土矿物是由基岩风化搬运而来，故了解沿海陆地基岩的岩石类型和岩性十分重要。稀土矿采、选、冶技术水平的提高与稀土矿勘查、开发水平的提高也是相互促进的。我国是稀土资源大国，近年来采、选、治水平突飞猛进，从1986年起，稀土产量已跃居世界首位。
Exploration of ore deposits of REE and research into the metallogeny help each other forward. Alkaline rock-and carbonatite-related ore deposits of REE are most important endogenic ore deposits of REE. They occur in composite intrusions in and near deep fractures at plate boundary. Shore REE placer is one of the most important exogenetic ore deposits of REE. It is of great importance to a search for primary ore deposits of REE. Mining,dressing and smelting technique of oretof REE and exploration-exploitation of ore of REE help each other forward, too. China is rich in mineral resources of REE, the exports of REE production leaps the first place in the world.
