| Accessory minerals may include sanidine, melilite, sodalite, perovskite, apatite, and chromite. |
| Early minerals, such as the chromium-bearing mineral chromite, crystallize early and are denser than the surrounding magma. |
| The plagioclase crystals would have formed subcircular lenses of anorthosite that punctuated background chromite accumulation. |
| Three oxide ore minerals form magmatic cumulates: chromite, magnetite, and ilmenite. |
| As a result, geologists long held the opinion that cumulates of chromite and other dense minerals formed only by sinking. |
| Unbrecciated diogenite that shows orthopyroxenes and chromite grains that are partially fragmented and deformed. |
