Mascot Mine, Gorham, Coos County, New Hampshire, USA
| Locality type: | Mine | |
| Classification | ||
|---|---|---|
| Species: | Siderite | |
| Formula: | FeCO3 | |
| Comments: | Identified by SEM-EDS at the UNO lab (Jim Nazimoff & Al Flaster), and by repeated visual and wet analysis. The SEM analyses showed that even the lightest colored specimens are Mn-rich: siderite var. manganoan. This species is probably the single "collectable" mineral found at the site as non-micro crystals (along with an occasional quartz crystal specimen...) | |
| Habit: | Typical clusters and vug linings of rhombic crystals, from micros to individuals to about 1.5 to 2 cm. | |
| Colour: | Dark brown to light tan, sometimes almost honey colored, often stained blue-black by Mn-O and having an sub-iridescent appearence. | |
| Luminescent properties: | none. | |
| Quality for species: | Good crystals or rich for species - important (!) | |
| Abundance at site: | Common | |
