The usually called “Kongtong Conglomerate”, possiblely aged middle-late of Late Triassic, is the facies change sediment of the Yangchang formation in the west margin of Ordos basin,and its component are mainly pebbles of limestone and sandstone. Outdoor investigation show that these pebbles resemble the limestone of the middle Ordovician Sandaogou formation and the sandstone of the lower Permian Shanxi formation separately. Further studies of the micro-petrography, the rare earth elements(REE)and the microelements also demonstrate the approximate result.
