垭头铀矿床控矿沉积相及成因

ORE-CONTROLLING SEDIMENTARY FACIES AND ORIGIN OF THE MINERALIZATION IN YATOU URANIUM DEPOSIT

垭头铀矿是湘西沅麻盆地白垩系红层中较为典型的沉积矿床,位于盆地东北缘,靠雪峰隆起,置于Z_b,(?)_(1x),地层之上。本文是在综合野外实践的基础上,研究矿床的沉积特点、控矿沉积相以及矿床成因。

Yatou uranium deposit is a more typical sedimentary deposit occurring in the Cretaceous red bed of Yuanma Basin in western Hunan and is located at the northern margin of the basin, adjacent to the Xuefeng uplift and in Z_b and (?)_(1z) series. On the basis of analysing field and practical data, the sedimentary features, ore-controlling sedimentary facies and genesis of the deposit are introduced more comprehensively.
