Major and trace element composition of olivine from magnesian skarns and silicate marbles
American Mineralogist, 2021 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 ...
