大陆铀成矿区大地构造类型及其简要评价

The Geotectonic Types of the Continent Uranium Region and Their Brief Evaluation

摘要: 铀资源量大于2万t的主要大陆铀成矿区约72处，形成于不同成矿时代，产于不同大地构造层内。本文以铀成矿区为载体，依据大地构造控矿观点，提出大陆铀成矿区大地构造类型划分，分出5大类15亚类27小类。大类划分是按成矿区大地构造层的属性不同，亚类划分是按铀成矿区的铀成矿时代差别，小类划分是按成矿区的局部构造及含矿主岩类别的区分，并对铀成矿区主要大地构造类型作简要评价。这种划分在进行铀成矿区评价时较为方便适用，有一定的参考意义。

Abstract: About 72 continental uranium regions with a uranium resource of more than 20,000 t are formed in different mineralogentic epoches and occur in different tectonic layers. Based on the geotectonic ore-controlling point of view, this paper proposes the classification of geotectonic types in continental uranium mining area, which is divided into 5 categories, 15 sub-categories and 27 subclasses. The classification is based on the different attributes of the geotectonic strata in the mining area, the sub-categories are based on the time of uranium mineralization in the uranium mining area, the subclasses are divided according to the local tectonics and the main ore-bearing rock types in the mining area, and the main geotectonic types in the uranium mining area are briefly evaluated. This division is convenient and applicable in the evaluation of uranium mining area, and has certain reference significance.
