In this work, the quantification of ternary mixture (aragonite, calcite and vaterite) was accomplished using micro Raman spectroscopy. Raman spectra were collected employing the DXR Raman spectrometer (Thermo Scientific) equipped with high resolution grating (1800 lines mm-1). All measured samples were simultaneously measured using X-ray powder diffraction and quantitative phase analysis was performed with the Rietveld method.
