Geochronological study of metasediments and carbon isotopes in associated graphites from the Sargur area, Dharwar craton: Constraints on the age and nature of the protoliths

207 Pb/ 206 Pb ages of detrital zircons from the graphite bearing metasediments of the Sargur area are determined using ion microprobe to constrain the probable depositional age. Zircon ages of the samples range from 2.3 to 2.8 Ga which are close to the reported metamorphic ages in the vicinity. Abs...
