Carbon and oxygen isotope data of whole rock carbonates from Mesoproterozoic
to Neoproterozoic Deoban Group of Uttaranchal Lesser Himalaya has been
investigated by Tewari (1997, 1998b, Fig.3). I3C values vary from -3.7 to +6.6% ...

To confirm the findings through C-isotope chemostratigraphy, ten representative
dolomite samples were analysed for C-isotopes. The carbon isotopic ratios are
significantly positive and quite consistent with the l3C (Carbonate carbon) values
