Orogenic peridotite massifs metasomatism

However, a few examples of metasomatism and chemical enrichment by alkaline, deep-seated melts have been described, notably in the St. Paul s Island oceanic peridotites, in the Atlantic Ocean (Roden et al., 1984) and in the Lherz orogenic massif and neighboring massifs such as Caussou, in the Eastern Pyrenees (Fabries et al., 1989 Bodinier et al., 1988, 1990).
