Description

FIR-MIR Raman bandlist of natural Ferroan Magnesite (0.05 < Fe < 0.5) at 295K

Number of bands

8

Comments

From a detailed analysis of the Raman bands along the whole siderite-magnesite solid solution (Schmitt et al. 2026) - The wide range of positions is due to the wide range of composition in Fe+Mn (5 - 50 at% of cations), plus some minor substitution by Ca and Zn (<1%).

Parent experiments

• micro-Raman emission spectra of Mg-Fe(-Mn) carbonates along the Magnesite-Siderite solid solution

Parent spectra

• MIR-FIR normalized Raman spectrum (532 nm) of Fe-Magnesite (Ojos Negros, Spain) - grain M2-G9 - Mg# = 52.4%
• MIR-FIR normalized Raman spectrum (532 nm) of Fe-Magnesite - grain M2-H4 - Mg# = 69.2%
• MIR-FIR normalized Raman spectrum (532 nm) of Fe-Magnesite (Felber Valley, Austria) - grain M2-H0 - Mg# = 74.3%
• MIR-FIR normalized Raman spectrum (532 nm) of Fe-Magnesite (Pfitsch Valley, Italy) - grain M4-G3 - Mg# = 82.8%
