(of a rock or mineral) containing iron and magnesium as major components.

- ‘Thus, in magma chambers dense ferromagnesian minerals may sink to form cumulate rocks at the base of the chamber, whereas in partial melting a lower-density melt may percolate upwards.’
- ‘The very low magnesium content of Lime Crest ferroaxinite may reflect the relative scarcity of ferromagnesian minerals in the granite.’
- ‘The rhombohedral phase usually occurs as large tabular inclusions near the rims of ferromagnesian phenocrysts.’
