• It has been suggested that the melt that formed the islands comes from a peridotitic source enriched by the addition of a slab-derived melt with subsequent open-system fractionation, resulted in the evolved andesitic adakites.
• However, this hypothesis does not explain the correlation between subducted young crust and adakite eruptions nor the fact that the lower Yb and Y in adakites suggest that garnet is stable in the source.
• Identification, petrogenetic and tectonic characterization of a variety of rock types from the Archaean greenstone belts of southern India such as ultramafic komatiites, high-Mg basalts, anorthosites, boninites, adakites, Nb-rich basalts, grey-wakes, banded iron and manganese formations, the distinct phases and types of the TTG gneisses and granitoides;.
• Chachani has erupted andesite and dacite, which define a potassium-rich calc-alkaline suite with unusual adakite characteristics; adakites are magmas that form when the downgoing plate in a subduction setting melts.
