南岭构造体系对铀矿的控制作用

南岭地区构造，除以纬向构造体系为主外，尚有经向、华夏及新华夏等构造体系。南岭地区铀矿矿点数量之多，矿床储量规模之大，以及矿床类型之全均为全国之冠，其与本区地质构造发展及各构造体系之间存在着空间分布或成生联系，表现为：构造体系控制着含铀地层与含铀岩体；构造体系的复合控制着铀矿田（区）的分布；不同构造剑系分别控制着不同类型的铀矿床；以及构造级别、序次及结构面的力学性质对铀矿体的控制等。

Nanling Structural Systems as Uraniun Ore-Controlling Structures

In Nanling area there are the meridional structural systems, the Cathaysian structural systems and the Neocathaysian structural systems etc. Besides the predominat-ing latitudinal structural systems. This area occupies the first place in chinafor the nu-merousness of uranium occurrences and the large reserves and wide variety of uranium de-posits, which are closely associated with and genetically related to the tectonic develop-ment and the various structural systems as demonstrated by the following facts:1)The structural systems control the uranium-bearing strata and igneous bodies;2)The com-pounding of structural systems controls the distribution of uranium ore fields(districts);3)Different structual systems control different types of uranium deposits;and 4)Uranium orebodies are controlled by structures of lower order and generation as well as by mechani-cal characters of structural planes.
