Four crystals of haemoilmenite (brown), showing reflection pleochroism from dark to light brown, carry abundance crystallographically oriented haematite (white) exsolution bodies. The largest haemoilmenite (right) contains an area (bottom right) of rutile (lilac-grey) surrounded by haematite (white, higher reflectance). Dark grey area (bottom right) is silicate and black areas are fractures.
