本文将铀矿床赋存的构造形态划分为层控、断控和体控三种模式。层控模式包括沉积成岩阶段形成的层状铀矿床、顺层发育的后生带状铀矿床和与不整合面有关的铀矿床;断控模式包括各种产于断裂带(层间断层除外)的铀矿床;体控模式的铀矿床则分为与侵入体构造和火山机构有关的两种情况。所有模式均具有三个特性,即模式保存的完整性,模式发展的阶段性和模式形成的复合性。铀矿床的构造模式特征对矿床评价具指导意义。
In this paper, the tectonic forms of uranium deposits are divided into three modes: layer control, fault control and body control. The stratigraphic modes include stratigraphic uranium deposit formed in sedimentary diagenesis, epigenetic uranium deposit in strata and uranium deposit associated with unconformity. The modes of fault control include various types of uranium deposits that originated in the fault zone except for interbedded faults Uranium deposits; and the body-controlled uranium deposits are divided into two cases related to intrusive structures and volcanic structures. All models have three characteristics, namely, the integrity of model preservation, the stage of model development and the complex formation of model. The characteristics of tectonic models of uranium deposits are instructive for the evaluation of ore deposits.
