摘要: The tectonic setting and source of the Paleo-and Mesoproterozoic magmatic suites in SW Amazonian craton revealed by integrated isotopic geochemical data allow correlation between accretionary mobile belts contemporary continental magmatism (e.g. rapakivi complexes) within foreland. may represent synorogenic response to high heat flow asthenosphere resulting from oceanic crust subduction, which led development successive Proterozoic arcs.
