Origin and geologic significance of Dual Seismic Discontinuities in the upper mantle

Journal article examining the origin and geological significance of dual seismic discontinuities in the Earth's upper mantle.

Cross-section diagrams of some types of orogen . Principal features of the various types of orogens. (A) Collision related. Collision orogens showing delamination of the crust. Delamination, or splitting apart of the crust is typical for collisional orogens where plate convergence brings two continental crustal sections into direct contact. Here the space between the delaminated crustal layers of the lower plate is filled by crust of the opposite, upper plate. This feature, also called “crocodil
