The oceanic basin was finally been closed to form a new unified continent in the end of Carboniferous, went through two periods of plate tectonic system and two times of main underthrust-collision orogeny.

Control of plate tectonics over evolution of petroliferous basins and characteristic of oil and gas distribution in China;

Charm of landing of plate tectonics on the continent as viewed from the study of the archipelagic arc-basin system;

Present-day mantle flow and its interaction with plate tectonics inferred from observational evidence;

In recent years, many Proterozoic ophiolites are identified,which indicate that modern plate tectonics could be extrapolated at least to the Early Proterozoic, and Wilson cycle has been operated since then.

Since the advent of plate tectonics, mountain-building is generally referred toas a result of collision between oceanic plate and continental plate or continentalplate and continental plate.

To divide plate tectonic units,as the author held,the four basic principles should be fol-lowed,that is,systematic principle,space-time principle,grade-order principleand synthetic principle.
