摘要
通过区域地质背景及矿化特征的阐述,在分析该区地质演化及含铀层岩相古地理的基础上,认为甘肃南部铀矿的形成与地质历史演化有着密切内在联系,铀矿化主要受控于中志留统每个旋回末期发育的硅岩、灰岩和炭质板岩层。
By studying the regional geological setting and mineralization characteristics,as well analyzing geological evolution and lithofacies paleogeography of south Gansu Province,it is supposed that the formation of uranium deposit in this area has relatives with geological evolution,uranium mineralization was controlled by silica rock,limestone,carbonaceous slate bed developed in the late period of each circle in the Middle Silurian Series.
