Anhydrite |
| CaSO4 |
| Orthorhombic |
Anhydrite is known only in a single small specimen found at Franklin in 1928. It is a small nodule, an inch across, enclosed in limestone, that appears to be a fragment of a carbonate vein. Its center is a compact, finely granular mass of pure pale-bluish anhydrite, bordered by a zone containing some gypsum plates in the anhydrite. A more distinct border wholly surrounding the anhydrite consists of pale-pink sussexite, and a thin film of pale-yellow serpentine separates the nodule from the enclosing fine-granular limestone.
