| 摘 要： | 通过综合区调，笔者认为赣杭构造带东段天姆尖盆地是一个大型炎山塌陷盆地，其铀成矿条件良好，是陆相火山岩型富大铀矿有利的找矿靶区之一。本文详细论述了天姆尖盆地的区域地质特征、盆地的基底与盖层特征，厘定了盆地的性质，并根据区域地球物理场特征推断盆地的深部地质结构，全面分析了该盆地的铀成矿条件，指出找矿前景。

| Abstract: | On the basis of comprehensive regional reconnaissance the author suggests that the Tianmujian basin located at the eastern part of Gan Han tectonic belt is a large volcanic collapse basin with good U metallogenic conditions, and one of the favourable target areas for volcanic type rich large U deposit. The paper detailedly describes the regional characteristics and the features of the basement and the cover of the basin, determines the nature of the basin, infers the deep geologic structures according to the regional geophysical field, analyses the U metallogenic conditions and proposes the U prospecting potential of the basin. |
