摘　　要：相山铀矿田其铀矿物主要与绿泥石、萤石和赤铁矿相伴生,根据矿石产出形态及围岩蚀变特征,并不能将其定义为部分人所认为的斑岩型矿床,而应属热液成因矿床。根据相山铀矿床的矿石及围岩蚀变带特征,建立了该矿床成矿反应体系,并通过总结前人在碳酸盐中碳氧同位素的研究,确定了在整个成矿过程中地幔流体物质的参与情况。根据国内外典型浅成热液型-斑岩型矿床的特点,判断相山地区具有很大的深部找矿潜力。As the Uranium mineral in Xiangshan Uranium Orefield is mainly associated with Chlorite, Fluorite and Hematite, according to the form of ore output and the alter- ation characteristics of wall rock, it cannot be defined as the porphyry deposit generally, but the hydrothermal deposit. Based on the ore and the alteration characteristics of wall rock, the ore-forming reactive system of Xiangshan Uranium Orefield is established and the role of the mantle-derived flu- id acting in the mineralizing process is determined by sum- marizing the studies of carbon and oxygen isotopes of the carbonate. According to the characteristics of the typical epi- thermal-porphyry deposit at home and abroad, it is conclu-ded that there is considerable prospecting potentiality in the deep part of Xiangshan area.
