| 摘 要： | 桃山铀矿田产于桃山复式花岗岩体内,岩体主体形成于三叠纪—早白垩世,在晚白垩世—古近纪,岩体内发育有NE向断裂构造和脉岩带;从北往南,依次形成了小布—麻田脉岩-构造带、王泥田脉岩-构造带、黄潭—岳源脉岩-构造带、西陂—上罗脉岩-构造带、鸡婆岭脉岩-构造带、王册脉岩-构造带,以及石源岭脉岩-构造带;主干断裂构造控制了脉岩-构造带的形成和发展。这些脉岩-构造带与铀矿化在空间上一致,时间上相近,是桃山矿田铀矿定位的重要因素之一,是铀矿找矿预测的方向。

| Abstract: | Taoshan uranium field is occurred in the Taoshan composite batholith in the central Jiangxi Province. The main body of the batholith was formed in Triassic—Early Cretaceous. In Late Cretaceous—Eogene, NE strike fault structure and dike belt were developed in the batholith. From the north to the south, there are successive Xiaobu—Matian dike-structural belt, Wangnitian dike- structural belt, Huangtan—Yueyuan dike-structural belt, Xibei—Shangluo dike-structural belt, Jipoling dike-structural belt, Wangce dike... |
