| Title | Graphite in a marble |
|---|---|
| Description | This is a specimen (9 cm across) of a graphite-rich marble. The graphite is scattered throughout and appears as silvery gray flakes. Besides graphite, this sample also contains white calcite and brown phlogopite. Most marbles contain more calcite (or dolomite) and less dark colored minerals than this specimen. Graphite is rather common, but generally only as small crystals making up minor parts of a rock. Where graphite is mined, it generally comes from massive veins. Graphite has the same chemical composition as diamond, but the two have radically different properties. |
