TL;DR: The Ethiopian plateau is made up of several distinct volcanic centres of different ages and magmatic affinities as discussed by the authors, and the three main types of magma have very different major and trace element characteristics ranging from compositions low in incompatible elements in the tholeiites [e.g. 10 ppm La at 7 wt % MgO (=La7), La/εb = 4.2], moderate in the alkali basalts (La7 = 24, La/β = 9.2), and very high in the magnesian alkaline magmas (

TL;DR: In this paper, the authors run 3D models by coupling PECUBE with a landscape evolution model (CASCADE) and show that lateral variations of the kinematics of crustal deformation and exhumation are likely.

TL;DR: In this paper, high-pressure and ultra-high-pressure rocks with origins in a variety of protoliths occur in various settings: accretionary wedge, oceanic subduction zone, subducted continental margin and continental collisional zone.

TL;DR: In this article, the authors proposed that the Neogene magmatic and metamorphic evolution of the South Asian margin was controlled by slab breakoff of the subducting Indian continental margin starting at about 25 Ma, based on available geophysical data from South Karakorum and South Tibet.

TL;DR: In this article, the authors studied the M.C.T. shear zone from the view-point of the quartz-rich rocks and used the preferred orientation study of their c-axes to predict the sense of shear for Himalayan thrusting in more than 80% of cases.
