摘　　要：前人对赣杭—武夷山铀成矿带进行了广泛的研究,取得了许多成果,推动中国东部铀矿找矿的进步。为探讨该成矿带的成矿规律,重点对赣杭铀成矿带、武夷山铀成矿带地层格架与地质时代、挤压构造事件的厘定、岩浆作用与热液型铀矿的关系开展深入研究,将赣杭—武夷山铀成矿带侏罗—白垩纪地层归纳为5个部分;赣杭—武夷山铀成矿带形成经过伸展—挤压—伸展多期次的构造韵律;火山岩与碱性岩浆为赣杭—武夷山铀成矿带中的铀成矿提供活性铀,成为储矿构造的重要条件。Previous studies on the Ganhang-Wuyishan uranium metallogenic belt have made many achievements and promoted the progress of uranium prospecting in eastern China.In order to explore the metallogenic regularity of the metallogenic belt,the stratigraphic framework and geological age of the Ganhang-Wuyishan uranium metallogenic belt,the determination of extrusion tectonic events,and the relationship between magmatic action and hydrothermal uranium deposits are studied in depth.The Jurassic Cretaceous strata in the Ganhang-Wuyishan uranium metallogenic belt are summarized into five parts.The Ganhang-Wuyishan uranium metallogenic belt formed a multi-stage tectonic rhythm of extension-compression-extension.Volcanic rocks and alkaline magma provide active uranium for uranium mineralization in the Ganhang-Wuyishan uranium metallogenic belt,and become an important condition for ore storage structures.
