| 摘 要： | 本文指出,我国南部某铀矿床产于MS花岗岩体内,其矿石矿物主要为硅钙铀矿和钙铀云母,偶而出现沥青铀矿。矿体产在花岗岩的低温辉沸石化晕范围内,其上部矿化主要发育钙铀云母,下部主要发育硅钙铀矿。矿石中铀镭基本平衡。经初步研究认为,本矿床应是在早期沥青铀矿化预富集的基础上,经辉沸石化及铀酰矿化而形成的内生铀矿床。

| Abstract: | The uranium deposit studied by the authors is located in a granitic massif (MS) with uranophane and autunite as main ore minerals Pitchblende is occasionally found The ore bodies exist within the halo of low-temperature stilbitization with the occurrence of autunite in its upper part and uranophane in its lower part. The ore is characterized by basic equilibrium between uranium and radium. The Preliminary geochemical study suggests that the deposit must have been formed by stilbitization and uranyl mineralization on the basis of pre-existing pitchblende mineralization hence it is an endogenic U-deposit. |
