本文着重论述挟持构造对铀矿田、矿床的控制作用,即①“成矿断裂挟持区”对铀矿田的控制;②“控矿断裂挟持带”对铀矿床的控制。强调挟持构造的控矿作用并不排除其它的构控作用。挟持构造的形成过程和控矿机制比较复杂,不是所有的挟持构造均能造成矿化的工业富集。成矿是多因素控制的,而挟持构造是控制矿场定位的主要构造因素。重视成矿的挟持构造研究,对找矿和成矿预测均具有一定的实践意义。
This paper focuses on the control of the hostage structure on uranium orefields and deposits, ie, the control of uranium orefields by the “hostage zone of metallogenic fault fracture”; and the control of uranium deposits by the “ore-bearing fracture hijacking belt”. Emphasize that the hostage control structure does not rule out the role of other structural control. The process of hostage structure and the ore-controlling mechanism are complicated. Not all hostage structures can cause mineralization in industrial enrichment. Mineralization is controlled by many factors, while hostage structure is the main structural factor controlling the location of the mine. It is of practical significance to pay attention to the hostage structure of mineralization and to prospecting and mineralization prediction.
