摘要:
欧亚大陆层状氧化带砂岩型铀矿床,集中分布在欧洲阿尔卑斯造山带和天山造山带的北缘带内。铀成矿作用在欧洲与海西期及阿尔卑斯期二次活化构造作用,在亚洲只与阿尔卑斯期(燕山和喜马拉雅期)活化构造作用,有密切的时空和成因联系。铀矿石年龄和主成矿期时代与活化构造幕合拍,铀矿床空间分布均在活化构造盆地内,铀矿体定位与含矿层位的活化构造掀斜导致的层状氧化还原过渡带有着成因联系。根据活化构造期岩浆作用强度,把层状氧化带砂岩型铀矿床的成因,分为无岩浆作用的纯层状地下水的、岩浆作用不明显但有热水作用叠加的、岩浆作用明显引起热水叠加的三种类型。
Abstract:
The study on space-time distribution of the layered oxidation zone sandstone-type uranium deposits in Eurasian continent shows that the metallogenesis is correlated with sec-ondary activated tectonics of the Hercynian and Alpine orogenic belt in Europe and Alpine(Yanshan-Himalayan)orogenic belt in Asia.The main metallogenic epochs are usually in co-incidence with the periods of mobilization,and the deposits are located in the activated regions.According to the intensity of activity,there occurred three kinds of mineralization:pure interlayer ground water,mixed fluid of ground water and thermal water not related to magma and thermal fluid which is mainly composed of thermal water related to magma.
