| Vein minerals are barite, calcite, chalcopyrite, kaolinite, pyrite, sphalerite, and wurtzite. |
| Associated minerals include various pyroxenes and zeolites in addition to the more familiar lazurite, sodalite, pyrite, and carbonates. |
| Where pyrite crystals have been lost, it can be seen that quartz did not penetrate pyrite. |
| It is dominated by the deposition of calcite with minor pyrite, marcasite, barite, anhydrite and gypsum. |
| The ore zone is a combination of veinlets, lenses, and nests of pyrite and quartz. |
| A quick, qualitative analysis of valves during SEM work confirmed the presence of pyrite and the calcium phosphate composition of the carapace. |
