Long history of a Grenville orogen relic – The North Qinling terrane: Evolution of the Qinling orogenic belt from Rodinia to Gondwana

The North Qinling terrane (NQT) is considered to be a relic of the Grenvillian orogeny and is related to the formation of Rodinia because of the extensive magmatism and typical amphibolite-facies metamorphism that occurred in the NQT at ∼1.0 Ga. It was also involved in the Qinling orogen in the early Paleozoic during the amalgamation of Gondwana, as indicated by a phase of ultra-high pressure metamorphism at ∼500 Ma. We provide a synthesis of...
