The rocks and isotopic age of collisional structures in Pamir Plateau recorded the movement of Indian plate towards Asian plate, which passed through 3 stages of subduction, collision and squeezing.

Large amount of isotopic age data achieved in recent 10 years in Hengshan & Wutai Mt.

Rock and isotopic age of the collision structures in Pamir region have recorded the movement of Indian plate toward Asian plate, which has experienced subduction and consumption of Neo-Thetys (113±1.

A series of the lava and the red strata up them in the west part of northern Dabie orogen were divided into Chenpeng Formation and Zhou Jiawang Formation,which belong to the early and late Cretaceous period,according to the conchostracans,the isotope age and the fossils of abundant dinosaur eggs and a few ostracodas.

Isotope age determination results show that the age of formation is 138 Ma for the 3-d member of the Zhangjiakou group volcanic rocks and is 133 Ma for the Huajiying group rocks.
