A huge thermal dome structure was firstly formed in continental crust due to rising of hot mantle plume during the Early permian, and graben and fault basin were further formed.
The thickness of continental crust is not only thicker but also less dense than that of oceanic crust. The average thickness of the continental crust is thirty-five kilometers, though it may be considerably thicker or thinner in particular regions.
HPM-UHPM registers the low thermal gradients and deep subduction of continental crust during the early stage of the collision process in Phanerozoic subduction-to-collision orogens.
Significant fluctuation with a time-scale of several years exist in the crustal movement, which might be a principal feature for the continental crustal movement;
The existence of NW-SE direction mantle flow under the continental crust in the north continental margin of South China Sea made the extension activities migrate from north to south.
Panxi Rift with the dome-shaped volcano pattern has undergone three evolutionary processes: the lithosphere dome by mantle bulge, the continental crust dome and the subvolcano-dome.
A stable area of continental crust that has not undergone much plate tectonic or orogenic activity for a long period.
The tin mineralization dies not depend on wall rocks in a certain extent, butchiefly relies on orogenic granitic belts of the obduction side of the continental crust.
This study provides new evidence for continental crustal growth in the central Asian orogenic belt during the Phanerozoic.
The data also imply that there are Meso- to Neoarchaean continental crusts in the source areas.
