Species: | Spessartine |
Formula: | Mn32+Al2(SiO4)3 |
Formation: | Primary |
Comments: | Reference includes a list identical to Schooner (1958) with no details. However, spessartine is very likely given the abundance of Mn minerals in this pegmatite and the orange-brown color typical of near end-member crystals analyzed at other Connecticut pegmatites. Schooner (1958) states: "collected a superb specimen of intergrown one inch orange-brown trapezohedra... resembling essonite". |
Habit: | trapezohedral |
Colour: | orange-brown |
Abundance at site: | Rare |
