Species: ALMANDINE Locality: Murphy Prospect, Springfield, NH Specimen Size: 3.2 cm crystal. Field Collected: Tom Mortimer Catalog No.: 1160 Notes: During a revisit to the "Murphy Prospect" in Sept., 2011, none of these garnets could be found. Recent information has indicated that there are two "Murphy Prospects" above the Globe Mine in Springfield. |

Species: ALMANDINE - Mn rich Locality: Joe Hill area, Springfield, NH Specimen Size: 3 cm specimen with broken garnet section. Field Collected: Tom Mortimer - April 2005 Catalog No.: 1702 Notes: Certainly, a poor garnet specimen, but the locality is of interest to NH collectors. Phillip Morrill, in his Mines and Mineral Localities of New Hampshire booklet states: "the Joe Hill farm may be where all collectors got their spessartites." The earliest report of a Springfield, NH spessartine occurrence is in Jackson's 1844 Geology and Mineralogy of the State of New Hampshire, pg. 183. Jackson states: "A most abundant supply of perfect crystals of this mineral [spessartine] may be obtained in a few hours, by breaking up the mica slate rocks of Springfield, NH. They occur in such profusion that the mica serves only to connect them together, so that on breaking the rock with the hands they fall out and are found to be perfect crystals. They are of perfect uniform sizes and about as large as a filbert. Rarely two crystals are united together. They possess a good color, but none of them appeared sufficiently rich for jewelry, and I have not had them cut so as to try their effect. To the mineralogist and crystalographer, they are interesting specimens." Many NH field collectors, including myself, have searched the "Joe Hill farm" area looking for the spessartine occurrence. None I am aware of have found it. Nor have I seen a spessartine sample perported to be from this locality. This garnet specimen, collected from a pegmatite ledge in the Joe Hill farm area, was analyzed (Joe Hill garnet analysis) and determined have a modest manganese content, but the Mn content is less than the Fe content, so it belongs to the almandine species. End member formulae are: Almandine Fe2+3Al2[SiO4]3 Spessartine Mn2+3Al2[SiO4]3 |
