Abstract：On the basis of the 1∶50 000 regional geological survey of Chahar Right Front Banner, Longsheng village, Xiguan village and Yongshan village, the authors preliminarily studied the characteristics of petrology, lithochemistry of rare earth and trace elements for Jurassic rocks in the Youloushan area. Enrichment factors are used to study mineralization. The enrichment and strong enrichment elements of Jurassic rocks are Ag, Pb, Zn, As, Sn, Sb, Hg, W, Bi and Mo, which shows that Jurassic magmatic activity provides the metallogenic hydrotherm. The characteristics of lithochemistry and geochemistry show that Jurassic rocks belong to aluminium saturation of super-saturation type of calc-alkaline series, and are the products in the encounter stage of magmatism. The rare earth elements distribution curve of porphyritic granite rocks exhibits a rightward steep dip, which shows the obvious separation between light and heavy rare earth elements. The rare earth elements distribution curve of quartz porphyry rocks exhibits a rightward gentle heeling, which shows an unobvious fractionation between light and heavy rare earth elements.
