近年来,在那些不含强还原剂(例如硫化物或有机质),并且未遭矿前蚀变的沉积岩中发现了后生铀矿化。在这些岩石中矿化的原因是有争议的。本文试以碧玉石英岩中的铀矿床为例加以讨论。所述矿区位于地背斜隆起的边缘。此地背斜由前寒武纪岩石组成,其上不整合地覆盖着寒武纪地槽型硅质岩和奥陶-志留纪陆源杂色碎屑岩。沿地背斜隆起和地槽凹陷的边界发育 In recent years, epigenetic uranium mineralization has been found in sedimentary rocks that do not contain strong reducing agents (such as sulfides or organic matter) and have not been pre-mined. The reason for mineralization in these rocks is controversial. This article will try to jasper quartzite uranium deposit as an example to be discussed. The mines are located on the margin of the uplift of the earth. The anticline is composed of Precambrian rocks unconformably overlain with Cambrian geosynclinal cherts and Ordovician-Silurian terrigenous variegates. Along the anticlinal uplift and trough depression border development
