The paper presents IR data on 4 species of marine molluscan shells collected from Vizag seashore. It is observed that irrespective of species, the mineralogical from of CaCO3 is aragonite. This is due to the fact that Mg present in the shell material acts as a regulator for the deposition of CaCO3. The paper suggests that infrared spectroscopy may be useful to provide valuable information in the biological system as it affords rapid qualitative and identification of biominerals.
