| Title | Quartz with dolomite |
|---|---|
| Description | This sample contains white quartz, SiO2 (silicon dioxide), and brown dolomite, CaMg(CO3)2 (calcium magnesium carbonate). Both are common minerals. Quartz is often white (or clear), but this hue of brown is a bit uncommon for dolomite. The quartz crystals in this sample have quartz's typical hexagonal prismatic shape. Dolomite typically forms rhombohedrons but some crystals (such as the ones in this specimen) curve into elongate saddle-shaped crystals. This specimen is 12.5 cm across. |
