The high Mg^# calc-alkaline and high Mg^# shoshonitic series in Qiangtang-Mangkang area indicate some intracontinental subduction happened ever in the middle part of the plateau, then the subducted slab broke off and asthenosphere was upwelled 30Ma ago, while the lithospheric mantle was melt to form low Mg^# peralkaline potassic, ultrapotassic series.

The mechanism of instability wrinkling in the process based on minimum energy principle is revealed, uniform mathematic description of the wrinkling wave on the strip of in-plane bending is established, the internal and external energy is deduced by energy method, and a uniform criteria of internal and external wrinkling is established; then how to combine the criteria with the FEM simulation system to make the numerical prediction of wrinkling into reality is also resolved in the paper. The effects of the forming parameters on the deforming result are analyzed by the uniform predict criteria. The results show as follows: as the compress width increase, external wrinkling first come into being, then internal winkling do, and finally in-plane bend occur; the loading wedge angle increase, internal winkling first come into being, thenin-plane bend do, and finally external wrinkling occur; in-plane bend is possible to occur with a increase of the strain-hardening exponent and the strength coefficient; and the effect of the friction factor may be ignored.
