Baryte from
Thomaston Dam railroad cut, Thomaston Dam, Thomaston, Litchfield County, Connecticut, USA
| Locality type: | Road Cutting | |
| Classification | ||
|---|---|---|
| Species: | Baryte | |
| Formula: | BaSO4 | |
| Formation: | Primary | |
| Comments: | Mostly it is found massive, but it also occurs in crystals up to one-half inch or more. May be confused with calcite, which occurs here as very thin tabular white crystals that mimic barite. Vogt describes baryte as "thin, white tabular crystals from a quarter inch to two inches across. While some of the barite fluoresces a cream color under shortwave ultraviolet light, other appears to be a salmon-pink." The latter is color is typical of calcite fluorescence. However, Vogt also states: "A bright yellow fluorescence of barite was observed when small crystals of honey-colored calcite were in close proximity to the barite. Some unusual forms of pyrite can be found in between the barite platelets. The mineral occurs associated with calcite, fluorite, galena, pyrite, quartz, sphalerite". Use acid to differentiate baryte from tabular calcite here. | |
