Raman-Spektroskopie
Carbonate Minerals
- System: LabRAM HR
- Time per point: 500ms
- Step size: 200 µm
- Data points: 5,041
Macro-scale mapping of a 14 mm x 14 mm area of a polished block of carbonate minerals, using DuoScan™ to create a 200 µm x 200 µm laser spot. Matching the acquisition step size, this ensures that the full surface area of the sample is analysed.
Minerals identified through their Raman spectra include:
- Red: Mg-Siderite (FeCO3–MgCO3 solid solution)
- Yellow: Calcite (CaCO3)
- Green: Dolomite (CaMg(CO3)2)
- Dark blue: Aragonite (CaCO3)
- Light blue: Siderite (FeCO3)
- Orange: Magnesite (MgCO3)
- Pink: Rhodocrosite (MnCO3)
