The Interrelations Between Collisional and Trap Magmatism of Taimyr Based on Geological Data and Modeling Results

Abstract

It is shown that in the Taymyr folded region the collision and trap magmatism are spatially combined. In time trap magmatism is associated with late-collision and post-collisional stages. Supercomputer modeling showed the possibility of mantle and crust heating in the late stages of collision, accompanied by basaltic magmatism in a quite large amount.
