A structural approach to the genesis of chrome ores within the Vourinos ophiolite (Greece): Significance of ductile and brittle deformation processes in the formation of economic ore bodies in oceanic upper mantle peridotites

•P changes could contribute to a “rapid” response of chromite precipitation.•Deformation controls the structural forms of economic ore deposits.•Deformation and influx could have influence the metallogeny of largest ore deposits.•Geochemical anomalies around the positions of chrome ores on all scales.•Variation in regional re-equilibration Τ and fO2 on the scale of complex.•Understanding geochemical anomalies is essential to chromite ore exploration.
