Реферат:	eng: A rare sodium carbonate nyerereite, (Na,K)(2)Ca(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 6.4GPa using a diamond anvil cell. The (4)(CO32-) band (710cm(-1) at ambient pressure) and (1)(CO32-) doublet (1077 and 1086cm(-1) at ambient pressure) demonstrated a positive pressure shift with d/dP irregularities at 0.5 and 3.0GPa. The obtained calibration was then used for residual pressure measurements in nyerereite-bearing inclusions in olivine from the Udachnaya-East kimberlite. Copyright (c) 2017 John Wiley & Sons, Ltd.
