N2 - A rare sodium carbonate nyerereite, (Na,K)2Ca(CO3)2, first found in unique natrocarbonatite lava of Oldoinyo Lengai volcano, also attracted a lot of attention as an inclusion phase in mantle minerals formed in the course of deep carbonatite magmatism. We measured the evolution of nyerereite Raman spectra under quasi-hydrostatic compression up to 6.4 GPa using a diamond anvil cell. The ν4(CO3 2−) band (710 cm−1 at ambient pressure) and ν1(CO3 2−) doublet (1077 and 1086 cm−1 at ambient pressure) demonstrated a positive pressure shift with dν/dP irregularities at 0.5 and 3.0 GPa. The obtained calibration was then used for residual pressure measurements in nyerereite-bearing inclusions in olivine from the Udachnaya-East kimberlite.
