Abstract
- The Mesoarchean-Neoarchean komatiites in Dharwar provide evidence for heterogeneous, hydrated Archean upper mantle trapped by ascending mantle plumes. They show that the precursor magmas of these rocks were derived by partial melting of a mantle wedge metasomatized by variable slab-mantle interactions and influx of slab-dehydrated fluids and sediments. Evolution of a Mesoarchean suprasubduction zone mantle wedge in the Dharwar Craton, southern India: Evidence from petrology, geochemistry, zircon U-Pb geochronology, and Lu-Hf isotopes. Petrogenesis of lamprophyres synchronous to kimberlites from the Wajrakarur kimberlite field: Implications for contrasting lithospheric mantle sources and geodynamic evolution of the eastern Dharwar Craton of southern India.
