圣拉斐尔隆起地区的铀矿床与上三迭纪琴尔建造中沉积物的沉积环境有密切联系。由低能环境(low-energy environments)沉积作用所引起的沉积结构似乎影响了铀的成矿作用。琴尔建造由三个向上变细的河积-湖积层组成。铀矿物富集在本地区最下层的底部,该处低能环境沉积物均与其他环境的沉积物成互层。在圣拉斐尔隆起琴尔建造露头的北部、西部和南部的地下均是勘探铀矿的有利地区。这一判断是根据沉积环境的空间分布和对琴尔建造自始至终全过程的沉积作用的模式做出的。
Uranium deposits in the uplifted area of San Rafael are closely related to the depositional environment of sediments in the Upper Tri-Jura Formation. The sedimentary structure caused by the deposition of low-energy environments seems to affect the mineralization of uranium. The Cher build consists of three upwardly stratified river-lacustrine deposits. Uranium is enriched in the lowermost bottom of the region, where low-energy environmental deposits are interbedded with other environmental deposits. Upstairs in the Ravell uplift Qin outcrop north, west and south of the underground exploration of uranium deposits are favorable areas. This judgment is made on the basis of the spatial distribution of sedimentary environment and the pattern of sedimentation of the whole process of Cirel’s construction.
