| 摘 要： | 本文运用伸展构造理论对河草坑铀矿田的构造特征进行探讨，厘定出会昌浅层次热隆伸展构造是由伸展构造核、环形剥离断层系和断陷红盆所组成。对会昌浅层次热隆伸展构造的形成与演化作了研究。论述了伸展构造与区域铀成矿的关系，认为剥离断层活动为区域铀矿化准备了有利的构造环境；构造－岩浆作用是导致区内铀矿化和造成不同类型铀矿化特征基本相似的根本原因。

| Abstract: | Applying the theory of extensional tectonics this paper discusses the tectonic characteristics of Hecaokeng uranium ore-field,and has determined that the Huichang shallow thermo-upwelling extensional tectonics are composed of a core of extensional tectonics,a system of ring denudational fault and a down-faulted basin. The paper has also analysed the formation and evolution of the Huichang shallow thermo-upwelling extensional tectonics,discussed the relationship between extensional tectonics and regional uranium metallogenesis. The activity of denudational faults prepares favourable tectonic environments for regional uranium mineralization,and tectono-magmatic activity is the principal factor leading to the formation of uranium metallogenesis in the region and the basic similarity in mineralization characteristics of different types of uranium deposits. |
