Metasomatized Kyanite-eclogites xenoliths from a southern Indian kimberlite

Kimberlites discovered so far in southern India are restricted to the Eastern Block of the Dharwar Craton and are distributed in three fields: Wajrakarur, Narayanpet, and Raipur. As summarized recently by Paul et al. (2006) and Patel et al. (2006), known kimberlite pipes in the Wajrakarur kimberlite field (WKF), which lies at the western margin of the Cuddapah Basin, occur in three clusters: Wajrakarur – Lattavaram (13 pipes, P-1 to P-13); Chigicherla (5 pipes, CC-1 to CC-5); and Kalyandurg (4 pipes, KL-1 to KL-4).
