Messelite from
State Forest Quarry No. 2 (State Forest #2 Mica Mine; Carini Quarry), Cobalt, East Hampton (Chatham), Middlesex County, Connecticut, USA
| Locality type: | Quarry | |
| Classification | ||
|---|---|---|
| Species: | Messelite | |
| Formula: | Ca2Fe2+(PO4)2 · 2H2O | |
| Comments: | "Many solid white or tan masses, with a curved lamellar structure, were collected; some were two inches across. The messelite was intergrown with siderite, or embedded in triphylite. Distinct crystals, with a pearly luster, were noted in vugs of the massive mineral." Schooner (1961). Associated with triphylite, siderite, strunzite, laueite, mitridatite, ludlamite, vivianite. A green mineral thought to be beraunite was tested by XRD (with some matrix) at the National Museum Prague (dr. Jiri Sejkora) and found to be "no beraunite but something similar to messelite". The green may be only a coating. | |
| Habit: | massive curved, lamellar aggregates, acicular microcrystals | |
| Colour: | white to tan, sometimes a green coating of an unknown. | |
| Abundance at site: | Rare | |
