Abstract
The use of FTIR spectroscopy to distinguish between some geologically important carbonate minerals (calcite - CaCO3), aragonite - CaCO3, siderite - FeCO3,
magnesite - MgCO3, and dolomite - CaMg(CO3)2 originating from Macedonia and to detect mineral impurities in them is considered. 1t was shown that the series of the
studied isomorphous calcite type minerals is an ideal test case for the evaluating the influence of the corresponding cation upon the band frequencies or the carbonate v3, V2
and v4 modes in their infrared spectra. It enables to distinguish the isomorphous calcite
type carbonates from one another. In the course of the quantitative determination of the composition of mixtures it is shown that the limit of detection of impurities of aragonite in the mixtures with calcite (or other calcite type minerals) is around I wt %. The spectra or natural calcite and siderite were compared to those of their synthetic analogues.
