Vp. Kovach et al., PAN-AFRICAN U-PB ZIRCON AGE FROM APATITE-MAGNETITE VEINS OF EASTERN GHATS GRANULITE BELT, INDIA, Journal of the Geological Society of India, 50(4), 1997, pp. 421-424
Pb-206/U-238 ages of zircon correspond to 502 +/- 3 Ma and Pb-207/Pb-2
06 ages are equal to 508 +/- 14 Ma. U-Pb isotopic study of the Kasipat
nam zircon has led to the recognition of pan-African thermal event in
the Eastern Ghats Granulite Belt, India.
