摘　　要：文章简要叙述了我国南方5省(区)富铀花岗岩和产铀花岗岩概况,详细讨论了产铀花岗岩的主要特征:断裂构造发育,蚀变作用非常强烈,经常有二云母花岗岩出现,中基性和酸性脉岩比较发育。正是这些特征,决定了它们产出铀矿床的能力。The paper briefly introduces the differences between uranium rich granite and uranium produc tive granite in the 5 provinces of South China, and dicusses their main characteristics in 4 aspescts, the urnium productive granite is highly developed in fracture, very strong in alteration, often occured as two mica granite and regularly developed with intermediatebasic and acid dikes. The above characteristics distinguish the uranium productive granite from the uranium rich granite.
