The West Qinling is located in the center of the West Qinling-Songpan continental tectonic node and it is also a part of Northeast margin of the Qinghai-Tibet Plateau (Zhang et al.,2001,2004).There are distributed different age red bed strata that include the Lower Cretaceous,Upper Cretaceous and Paleogene-Neogene in West Qinling Mountains (Bureau of Geology and Mineral Recourses of Gansu Province,1989;Zhang,1992).Detail investigation on these different age red bed strata could provide the geological constraint to better understanding the remote tectonic response to collision of the Indian plate and Asian plate since Cenozoic,and the relation between the deep dynamics and shallow crust deformation.
