Abstract
Plutonic and volcanic assemblages in the Central Asian fold belt provide a clue to geodynamic reconstructions of the Paleoasian ocean which existed in its place. Some assemblages bear clearly pronounced signature of their geodynamic environments and serve as indicators. Assemblages that originated in oceanic, island-arc, collisional, and postcollisional settings differ in specific structural-magmatic zonation.
