Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic.
