| 摘 要： | 就全球而言,前寒武纪是铀元素的一个非常重要的成矿期。华北地台是我国出露面积最广、形成时代最老、具有找矿前景的唯一占地台。在综合大量普查、区调资料的基础上,本文详细地论述了华北地台的基本地质特征,并与国外主要产铀占地台进行了对比,强调了地台基底,即原始古陆壳演化成熟程度及成熟期早、晚与铀矿化的关系。据此、并参考其它条件将华北地台划分为6类地区,指出了这些地区的不同找矿前景以及应着重寻找和探索的铀矿类型。

| Abstract: | So far as the whole globe is concerned, the Precambrian is the most important uranium ore-forming period. The North China Platform is a unique one with the largest outcropping area, the oldest formation age and is, consequently, more perspective for uranium. On the basis of synthesizing a great amount of the data accumulated during the prospecting and regional reconnaissance, the main geological characteristics of the North China Platform are given in detail in the paper. Comparison is made with the main uraniferous old platforms in other countries, and the emphasis has been put on the relationship between the "degree of maturity" and "maturity period" of the platform's basement, i. e. the relationship between primary continental crust, evolution and uranium mineralization. According to the principle abovementioned and taking into consideration of other conditions, 6 categories of the regions can be recognized in the North China Platform, and the different exploration prospect, the types of uranium deposits which should be explored in these regions are also indicated. |
