Web11 Apr 2024 · Thrusting and folding in the accreted oceanic plateau has been accompanied by greenschist- to amphibolite- facies metamorphism. The lack of the HP/LT metamorphism (blueschist-facies rocks) in the Fariman Complex, which would usually be expected for a subduction zone, possibly due to the slow exhumation rate, which could not rapidly … WebSubduction zones can create beautiful landscapes such as mountains; however, they are also dangerous regions. Subduction zones occur because one of the plates that collide with other, in convergent plate boundaries, is of higher density. Hence it sinks into the earth back to the mantle (lecture 3, slide 24-26).
