Chromitites from a single section through the mantle in the Oman ophiolite are of two different types. Low-cr# chromitites, of MORB affinity are found in the upper part of the section, close to the Moho. High-cr# chromitites, with arc affinities are found deeper in the mantle. Experimental data are used to recover the compositions of the melts parental to the chromitites and show that the low ...

1. Introduction. The fate of chromium from its mantle source and its concentration by the crystallization and accumulation of chromite in cooling magma bodies is a long-standing poorly understood process of the magmatic history of mafic and ultramafic rocks (e.g. Bowen, 1928; Lombaard, 1956; Stoll, 1958), and is still the matter of intense discussions (cf. Arai and Miura, 2016 and references ...
