Species: SPESSARTINE Locality: Outcrop above Ore Hill Mine, Warren, NH Specimen Size: 2.8 cm specimen - broken crystal section of orange spessartine with manganese oxide coated outer rim. Field Collected: Tom Mortimer Catalog No.: 1701 Notes: These garnets were collected from a quartz ledge outcrop just above (uphill) the Ore Hill Mine. Spessartine, the Mn garnet, Mn2+3Al2(SiO4)3, was confirmed by EDS analysis. Not particularly attractive specimens, but unambiguously spessartine. Photo taken in natural sunlight. |

I am thankful to have collected several samples before it disappeared below the surface! |
