| Title | Siderite from Allevard, France |
|---|---|
| Description | Siderite is iron carbonate. It is closely related to calcite but contains iron instead of calcium. It generally forms massive or fine grained samples like the one shown here. A close look at this specimen reveals some crystal faces and rhombohedral cleavage, typical of the calcite group of minerals. Siderite is, in some places, mined as an ore of iron. This specimen is 9 cm across. |
