underplating

The crust mantle transition in the west is considerably thicker than in the east, probably due to different extents of magmatic underplating.

西部壳幔过渡带较厚而东部较薄，反映两地不同的岩浆底侵作用程度。

Magma underplating and subsequent lithospheric extension could have been the geodynamic setting responsible for the voluminous magmatism and large-scale mineralization.

岩石圈伸展及幔源玄武质岩浆底侵作用可能是区域上大规模岩浆活动与成矿作用的深部地球动力学因素。

Underplating of basic melt beneath the crust is one of the most important patterns of crust growth and represents an effective material and energy transfer from the mantle to the crust.
