Hi Akshay Perhaps you could try Mutvei´s solution, have a look to this paper: Schöne, B.R., Dunca, E., Fiebig, J., Pfeiffer, M., 2005. Mutvei´s solution: and ideal agent for resolving microgrowth structures of biogenic carbonates. Palaeogeography, Palaeoclimatology, Palaeoecology 228 (1-2), 149-166. There is also Feigl solution but this is only to discriminate between aragonite and calcite. I think Mutvei´s is the right choice to examine growth increments. I hope this helps.
