Hematite is an ore of iron. It is a dark red rock from which we get iron. It has a red or brown colour with an earthy lustre. It is a heavy and usually hard oxide mineral that constitutes the most important iron ore. It is derived from the Greek word "blood" in allusion to its red colour. It …
distribution of magnetite + hematite and magnetite + ilmenite ( Fig.2 A). In addition, magnetites show exsolution texture with hematite (Fig.3 A), ilmenite or ulvo-spinel, hematite or sphene and rutile. Titano-magnetites are criss-crossed by exsolved rutile needles (Fig.3 B). Ambolgarh bay is marked by the domination of pure magnetite (Fig. 2 A).
