摘要
相山铀矿田是我国著名的火山岩型热液铀矿田。作者对矿田4个有代表性的铀矿床的赋矿主岩、铀矿石、沥青铀矿样品稀土元素地球化学特征进行了研究，探讨了其成岩、成矿的物质来源，揭示了两种不同地球化学类型铀矿床的稀土元素与铀矿化呈正消长关系，尤其是富矿床中铀与重稀土元素，主要来自深部原生流体，并呈现出共沉淀的特点，含铀热液分异演化愈强，则铀矿化愈富。
Abstract
Xiangshan Uranium ore fieled is a famous Volcanic type hydrothermal uranium ore field. The author studysgeochemical character of samples of REE of 4 reprentive uranium ores,of which are ore-host rock, uranium mine andpitchblende. This paper discusses material resource of rock-forming ore-forming, unveilings REE of uranium ore andmineralization of uranium of two difference geochemical types of mine,bring out relation of direct ratio, especialy urani-um and heavy REE in rich mine ore, which come from inner oviginal fluid and bring ont Co-precipitation. The strongeruranium-hydrothermal differntiation evolution is, the richer minerarli zation of uranium is.
