Olivine is a major rock-forming mineral in various magmatic and metamorphic rocks and the upper mantle. In this paper, we present the first high-precision analyses of olivine from 15 samples of magnesian skarns and silicate marbles (MSSM) from the collection of the Fersman Mineralogical Museum (Moscow, Russia). Mg# [Mg/(Mg+Fe 2+ )·100, mol%] of olivine from the samples studied varies from 86 to nearly 100. The main distinctive features of the olivine are anomalously low contents of Co (&lt;51 μg/g), Cr (&lt;5 μg/g), and Ni (&lt;44 μg/g) and high content of B (23–856 μg/g), which correlate with host-rock compositions. Phosphorus (5–377 μg/g) incorporation in olivine is charge balanced by the incorporation of Li (0.15–61 μg/g) and Na (&lt;14.3 μg/g). Y and REE contents exhibit positive correlations with Na, which suggests that REE incorporation into MSSM olivine could occur via charge-balanced coupled substitution with Na at low temperature and low  a  SiO2  conditions during MSSM formation. The documented compositional features of olivine from magnesian skarns and silicate marbles can help reconstruct the genesis of the host-rocks and identify xenocrysts of MSSM olivine in magmatic rocks.
