BaFe[CO3]2, a new double carbonate from the norsethite-type family of carbonates, was recently discovered and synthesized at high-pressure-temperature (high-PT) conditions. Two polymorphs of the new double carbonate were identified belonging to the R

Raman and mid-infrared (MIR) spectra have been measured on BaMn(CO 3 ) 2 , an ordered double carbonate, synthesised at low and at high pressures and temperatures (1 atm, 21 °C and 15 kbar, 510 ± 10 °C, respectively). The results show no significan

Following a tentative evidence for the occurrence of low-temperature barium manganese(II) carbonates in brackish sediments of the Baltic Sea, a stoichiometric double carbonate, BaMn[CO 3 ] 2 , was synthesized from aqueous solutions at ambient tempera

The effect of cationic substitution on the mid-infrared absorption spectra of synthetic, and natural inorganic and biogenic MgCO3-CaCO3 solid solutions (Mg calcites; space group R3c; 0–23 mol% MgCO3) is investigated, and the results are compared to

The infrared spectroscopic measurements of synthetic and natural carbonate samples show that significant frequency shifts in the v2 and v4 vibrational bands of the carbonate ion group occur in the calcite-rhodochrosite and calcite-magnesite mineral s

The FTIR spectra of synthetic BaMg(CO3)2 (norsethite) are measured at ambient temperature and atmospheric pressure, and the influence of formation conditions on the FTIR spectra is investigated. The results are compared with those for natural norseth
