Abstract:
Based on geological survey and analysis of petrology, lithogeochemistry, geochemistry of REE and microelement,the authors study metallogenic characteristics of V ore deposit in the Xianghe area of Shangnan County, Shaanxi, and discuss its genesis.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. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics. These all suggest that V ore deposit has the characteristics of submarine hydrothermal spring.
