Oxides Mineralogy4Kids

The minerals that make up the oxide class include those in which oxygen is combined with one or more metals. The minerals are very diverse in their physical properties they can be quite hard (H=9) and quite soft (H=5) and the colors can range from black to very colorful.

Hematite

Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 176;C (1,740 176;F).

MAGNETITE (Iron Oxide) Amethyst Galleries Mineral Gallery

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
