某地泥盆系具有分布广、沉积相复杂、含铀层位多的特点。铀矿在空间上的分布受古地理环境的控制,矿床(点)多数产在古陆边缘浅海的海湾地区;位于隆起带与拗陷带的过渡部位,由南向北含铀层位有逐渐升高的趋势。鉴于某地中、上泥盆统的区域含铀性,因此对该区泥盆纪岩相古地理的研究,是寻找本区泥盆系铀矿的重要课题。 Some Devonian has a wide distribution, sedimentary facies complex, containing many uranium layers features. The spatial distribution of uranium deposits is controlled by paleogeographic environments. Most of the ore deposits (deposits) occur in the Gulf with shallow sea at the edge of the ancient land. At the transitional part of the uplift and depressions, uranium deposits gradually increase from south to north. Increasing trend. In view of the fact that the middle and upper Devonian areas contain uranium, the study of the Devonian lithofacies palaeogeography in this area is an important issue for finding Devonian uranium deposits in this area.
