Devonian continental arc intermediate-felsic magmatism in the Gorny Altai terrane, northwestern Central Asian Orogenic Belt: Heterogenous crustal melting and input of mantle melts

Devonian intermediate-felsic igneous rocks are widespread in the Gorny Altai terrane and they were suggested to form in a continental arc setting that was built on the late Neoproterozoic to early Ordovician Kuznetsk-Altaiintra-oceanicsubduction-accretion system (KAIOSS).1 Petrogenesis of these rocks will not only provide information on geodynamic mechanisms for continental arc magmatism but also shed light on how accretionary orogens can be...
