Transformation of Fe-Ti gabbro to coronite, eclogite, and amphibolite in the Baie du Nord segment, Manicouagan Imbricate zone, eastern Grenville province: evidence for high heat flow in the lower crust during orogenesis
Fe-Ti gabbro from the Baie du Nord Segment of the Manicouagan Imbricate zone, metamorphosed under high-P-T conditions during the Grenvillian orogeny, has been the focus of a detailed micropetrological study. Textures and mineral chemistry suggest that the mineral assemblages represent progressive stages of metamorphic transformation resulting in the formation of coronas, pseudomorphs after igneous phases (transitional), and true granoblastic ...
