摘要
乌克兰沉积盆地铀矿床主要分布于第聂伯(Dnieper)盆地和第聂伯-顿涅茨(Dnieper-Donets)盆地,铀矿化类型主要有底河道砂岩型、含铀地沥青型、沉积改造型和断控砂岩/次火山岩型,含矿层位有泥盆系、石炭系、上二叠统和下三叠统、古近系等。文章分析了第聂伯盆地和第聂伯-顿涅茨盆地地质背景,阐述了产于两大盆地铀矿床基本特征,总结了沉积型铀矿床时空分布特征,建立了相应铀成矿模式,对我国沉积盆地铀矿找矿具有借鉴意义。
Uranium deposits in Ukrainian sedimentary basin are mainly distributed in the Dnieper basin and the Dnieper-Donets basin.These deposits can be divided into basal-channel type,uraniferous bitumen type,reformed sedimentary type and fracture-controlled impregnation sandstone/subvolcanic type.The ore-bearing strata extend from Devonian,Carboniferous,upper Permian and lower Triassic to Paleogene etc.The geological backgrounds of both Dnieper basin and Dnieper Donets basin has been described,and basic characteristics,temporal and spatial distribution of the uranium deposits have been illustrated,and corresponding uranium metallogenic models established,which are of significant for uranium resource exploration in similar sedimentary basins.
