sing the information of remote sensing and combining with the sedimentary formation analysis to pick out and study chronostratigraphic interface in cretaceous period basin in the course of studying intracontinental deformation evolution about North-eastern Jiangxi Jiangnan orognic belt and filling sequence of Xinjiang basin. Since three types of chronostratigraphic interfaces (Paleostructure interface, large regional erosional unconformites and overlap interface) have been picked out, it guarantees that the analysis of basin sedimentary facies is right. We can rebuild filling sequence and tectonic evolution stage of basin according to them. The method will become a new kind of methods in the course of terrestrial basin analysis in the future. It can push on founding method system of double mapping on terrestrial basin in 1:50 000 regional survey.
