摘要
本文论述了广西大地构造的特点及其演化规律,其中讨论了古陆壳其底存在的可能性,并提出了右江和钦州断拉谷型地洼的新概念。把构造运动与物质运动结合起来,探索区内铀矿床的形成特点及其时空分布规律,特别是地洼期的构造活动对铀元素的富集成矿起了至关重要的作用。
This paper discusses the features and evolution of the tectonics in Guangxi and the possibility of the existence of the ancient continental crustal basement, and advances a new concept about the Youjiang and Qinzhou aulacogen type depressions. The author combines the tectonic movement with the material movement to study the features of the formation of uranium deposits and their temporal-spatial distribution in the region. Especially the tectonism at the geodepressional stage played a key role in the concentration of uranium and formation of uranium deposits.
