Abstract: Abstract The question of whether continental subduction processes in collisional orogenic belts can trigger wide-spread mantle metesomatism and crustal material recycling remains unresolved. Miocene (25–8 Ma) ultrapotassic rocks in southern Tibet are the only mantle-derived magmatic… read more here.
