Abstract: Plate boundary is often sedimentary basin boundary. Different plate boundary takes different control actions on sedimentary basin. Therefore, the study on the identification plate boundary sedimentary basin is very important. Plate tectonics are three different mechanical properties of its boundary with the adjacent plate with zoning, so ancient and recovery partition plate is identified with the identification of ancient plate boundaries closely linked. However, it is precisely on this fundamental issue where there is a need to look at. Because the so-called boundary is not really determined by plate boundary that divided up the bulk of the plate but not truly Asian plate, the plate and the secondary block, rock. Therefore, in the study of ancient plate, the first problem is to identify the real plate boundary to suture, subduction zones, and expanding boundaries and transform boundary. When plate tectonics in the boundary school division of the plate is determined by a series of geographical, geological, seismic, geophysical and other signs; and for ancient plate boundary is determined, geomorphology, geophysics, seismology methods and logo on the petrology, structural geology, geography and ancient methods of ancient plate replaced by a sign which petrology has special significance.
