• Carbonates - Calcite, Dolomite
• Sulphates - Barite, Celestite, Gypsum (var. Selenite)
• Sulphides - Galena, Marcasite, Pyrite, Sphalerite
• Halides - Fluorite
• Oxides - Magnetite
• Other - Fossils (coral), Hydrocarbons

Comments:

1. Dolomite is whitish or pinkish. Unusual tiny saddle-shaped crystals are made of small misaligned blocks that produce curved crystal faces.
2. Sphalerite is generally lighter in colour than Dundas sphalerite and appears a gemmy yellow colour.
3. The barite is very white and platy when crystallized.
4. Very sharp octahedral galena crystals have been found.
5. Vugs with nice associations of galena, barite, marcasite and dolomite occur.
6. Most crystals are small and suitable for micro-mounts.
