摘　　要：粤北地区是中国花岗岩型铀矿最为重要的大型矿集区,在开展花岗岩型晶质铀矿的一般矿物学特征、矿物组合特点、产状及成因等方面进行综述的基础上,粤北石人嶂钨矿晶质铀矿的检测研究,发现晶质铀矿经常与磁铁矿、钛铁矿、黄铁矿、独居石、错石、磷灰石、磷钇矿等副矿物共生。在副矿物为钛铁矿-独居石型花岗岩中,晶质铀矿含量较高;晶质铀矿产出在矿物粒间、裂隙以及矿物的边缘。晶质铀矿的形态、含量、成因与地质条件关系的深入研究,必将为寻找晶质铀矿提供帮助。The northern Guangdong is the most important large concentration uranium area with granite, in the summary of the characteristics of general mineralogy . mineral combination, occurrence and causes, and in the research of ulrichile with detecting in north of Guangdong, it found that ulrichile often symbiotic with the deputy minerals of magnetite, ilmenite, pyrite, monazite, apatite. Xenotime and so on. The contents of urichile is higher in the graite of ilmenite--monazite; The ulrichile growth in intergranular, fissures and the edge of mineral. The deeply research of relation, which hetween the urichile of form. content, causes and geological conditions, all that will provide help for search ulrichile.
