Haemoilmenite comprises an ilmenite host (pink-brown) with exsolution bodies of haematite parallel to (0001) of the host ilmenite. The larger haematite bodies themselves carry further ilmenite exsolution bodies (centre) and rutile laths (lilac-grey, oriented cast-west, centre right). Later incipient alteration along fractures (black) has resulted in poor polishing.
