In Yinchanggou lead-zinc mining area, Ningnan county, Sichuan province, there are many cherts in Dengying formation of upper Sinian series. By means of research on geological survey on field, petrology, major elements, trace elements and rare earth elements of the cherts, its proved that the cherts are chiefly composed of opal, jade and quartz, total amount of rare earth elements of the cherts for 1.36× 10-6, which is the light rare earth enrichment. For Fe/Ti is between 48.751and 194.44, (Fe+Mn)/Ti between 51.143 and 197.22, Al/(Al+Fe+Mn) between 0.03 per cent, the cherts is mainly formed by hydrothermal sedimentation.
