Geodynamic significance of S-type granites in circum-Pacific orogens
In Phanerozoic circum-Pacific orogenic belts, most "post-collisional" S-type granites and associated high-temperature, low-pressure metamorphic complexes formed during early arc extension. The granites are part of a tripartite association consisting of (1) inboard S-type granite, (2) outboard oceanic arc, and (3) intervening, turbidite-filled backarc basin. S-type granites herald the formation of new outboard oceanic arc and extensional backarc systems, but thickening of a preexisting,...[Show more]
