摘　　要：善堂庵地区处在控制相山铀矿田富大矿床产出的邹家山-石洞断裂的北东向延伸端,区内主要发育东西向和北东向断裂。东西向断裂是控岩、控矿构造(早期控岩、晚期控矿);北东向断裂产状较陡,深切基底,成矿期活动强烈,常常与之前的东西向构造复合,深部流体和含矿热液沿其上升,形成较好的铀矿化。善堂庵地区铀矿化主要受花岗斑岩体及北东向巴泉-善堂庵断裂、邹家-布水断裂控制,区内多期、多序次构造发育,热液活动强烈,斑岩体广泛分布,铀成矿地质条件优越,具有良好的成矿远景。Shantang'an area is located in the extending part of Zoujiashan-Shidong fault which controlls the distribution of rich and large uranium deposits in the Xiangshan orefield,Fractures in this area are mainly in north-east strike and east-west strike.East-west fractures controlled the lithology in the early and mineralization in the later.North-east fractures are steep in occurrences and penetrate the base rock in the deep,the NE striking fractures activated strongly in ore-forming period and often coupled with the early formed EW fracture and acted as the channel of deep fluid and ore-bearing hydrothermal transformation which resulted in the formation of uranium mineralization.In Shantang!an area,uranium mineralization is mainly controlled by granite porphyry and the above mentioned fractures.In this area,fracture of multi-period and multi-order,strong hydrothermal activities and porphyry rocks are widely distributed which indicate the favorable geological conditions for uranium mineralization and good exploration prospect.
