本文通过对湘南经向构造带北段的遥感地质解译,发现了具有环形影象特征的古盆、古盆盆缘及其附近爆花点状影象的古岩溶,并阐述了它们在空间分布上与铀矿化有着较为密切的关系。文章在分析该区经向构造紧密褶断带和新华夏系构造强烈活动的基础上,强调了构造体系的复合。从而展示了古盆、古岩溶空间分布上的构造有利部位。华南多数大、中型铀矿床、在空间分布上显示了与NNE向中、新生代断拗红盆有着某种内在联系,作者就断拗红盆对铀成矿的机理进行了探索。并提出在该区一定的标高和距断拗红盆的一定范围内为理想的找矿区域。
In this paper, by means of remote sensing geologic interpretation of the northern segment of the Jingxiang tectonic belt in southern Hunan, paleokarst features of the ancient basin, the basin edge of the ancient basin and the popping-point image of the vicinity of the ancient basin have been found, and their spatial distribution Distribution and uranium mineralization are more closely related. On the basis of analyzing the intense tectonic fold-thrust zone formed in the meridional direction of the area and the strong activity of the Neo-Huaxia System, the paper emphasizes the compounding of the tectonic system. This shows that the ancient basin, ancient karst spatial distribution of structurally beneficial parts. Most of the large and medium-sized uranium deposits in southern China show an intrinsical connection with the NNE to Mesozoic and Cenozoic faulty red basins. The author explores the mechanism of uranium metallogenesis by the fault-depression red basin. It is also proposed that it is an ideal prospecting area within a certain elevation of the area and within a certain range from a broken basin to a red basin.
