摘要
文中将西北地史上所出现的红层划分成6个红层期,并探讨和研究了红层在铀成矿过程中所起的作用及内在联系。明确指出铀矿床与红层(盆)在形成时间上同时,在空间分布上相伴生;铀矿化主要与干热气候条件下形成的陆相红层有关。在综合分析的基础上提出了红层期成矿的理论及与红层(期)有关的铀成矿模式。
Uranium deposits are related to some extent with red beds, which have played an mportant role in uranium mineralization. In this paper, the red beds that have appeared in eological history of Northwest China are divided into six periods, and the role of red beds in ranium mineralization and the internal relations between them are discussed. It is pointed out nequivoally that temporarily uranium deposits were formd simultaneously with red beds and patially they are associated with each other. Uranium deposits are bound up mainly with ontinental red beds formed under the condition of dry and hot climate. Red beds are surely xistent wherever ore deposits are found, but not necessarily vice versa. On the basis of an ntegrated analysis, the uranium metallogenic theory and metallogenic model related to red bed eriods are presented.
