Abstract：Sandstone-type uranium mineralization were developed in the Wulunguhe Formation at the Dingshan area, Junggar basin. The sedimentary provenance and tectonic setting are carried out in order to understanding the exploration potential in the area. In these study, 32 samples were performed for elemental geochemistry analyses. The results show that composition of such sedimentary rocks is dominantly originated rom felsic volcanic rocks and andesite in continental island arc. The North Junggar Ocean was developed in Cambrian-Early Silurian period and formed intermediate-felsic intrusions in Caledonian continental area, whereas the Kalameili Ocean experienced extension-compression cycle and formed intermediate-felsic plutons at the variscan continental arc. In Neogene, weathering and erosion of rocks of both arcs resulted in the deposition at the Wulugu area, forming the Wuluguhe Formation.
