【摘要】 笔者利用遥感图像，并结合野外调查对武夷山西南段桃溪环形构造进行了解译分析，认为该环形构造是一个呈多层偏心式展布的中型环形构造，是在不同时期地壳局部隆起和旋转上升运动的相继作用下形成的。它对铀矿化的空间分布起着重要的控制作用，已知铀矿床（点）或矿化异常区、片有９７％以上分布在环形构造各层环及其边缘地区，并受其与线性构造带交切复合部位的控制。研究探索这类环形构造的特征，尤其是环形构造与矿产产出的关系．对指导矿产预测有较大的实际意义。更多还原

【Abstract】 Taoxi annular structure in the southwest section of Wuyishan has been interpretated and analyzed by the author using remote sensing image and combinating with the field investigation. The author holds that this structure tea middle scale annular structure distributed as multilayered eccentric style,formed as a result of the local elevation (uplift) and rotational raising in succession in the crust of different stages.So, it plays an important controlling role on the spacial distribution of uranium mineralization. It is known that 97 percentage of uranium deposits (occurrences) or anomalous areas and sheets of mineralization are distributed in each rim clayer and their marginal (peripheral) area, and controlled by their composite part intersected with tineament zone. Therefore, it is of actual significance for conducting the prognosis of minerals by studying the features of this kind of structure, especially the occurrence relation between the structure and minerals.更多还原
