A chromite occurrence called the Sabantuy paleoplacer was discovered in the Southern Pre-Ural region, at the east edge of the East-European Platform in the transitional zone to the Ural Foredeep. A ca. 1 m-thick chromite-bearing horizon is traced at a depth of 0.7–1.5 m from the earth's surface for the area of ca. 15,000 m 2.

Podiform chromite deposits are lenticular, chromite-rich autoliths in deformed dunites and harzburgites of ophiolite complexes. The ophiolite association is assumed to be created along accreting plate boundaries in the oceanic lithosphere. It is suggested that podiform chromite deposits form as magmatic cumulates in elongate …

Chromite (and the closely related magnetite) phenocrysts in extrusive, glomeroporphyritic, mafic rocks commonly form clusters that appear in thin section as elongate chains ( Dick & Bryan, 1978; Bannister et al., 1988; Roeder et al., 2001; Godel et al., 2013) ( Fig. 1a and b ). Such chains may also be present as inclusions in olivine ...
