Notes. Like rutile, ilmenite is quite variable in nature.Actually, more variable since it would likely come from the same deposit, it being the more iron-stained part. You can tell the difference between granular rutile and granular ilmenite by doing a smear test against an abrasive surface (i.e. an unglazed white tile).
