Species: DRAVITE Locality: Tower Hill Rhodonite Locale, Hinsdale, NH Specimen Size: Zoom view of 3 cm dravite crystal in specimen 1480. Field Collected: Tom Mortimer Catalog No.: 1480 Notes: Dravite verified by EDS analysis. Note in the analysis plot, the Mg content is much higher than the Fe content. This Hinsdale dravite is the closest to the pure dravite tourmaline end member of any NH dravite known to the author (Tom Mortimer). |

Species: RHODONITE Locality: Tower Hill Rhodonite Locale, Hinsdale, NH Specimen Size: 6 cm specimen with pink bands of unweathered "rhodonite." See notes below. Field Collected: Tom Mortimer Catalog No.: 1455 Notes: This is the "rhodonite" from the Hinsdale, NH rhodonite deposit. An EDS analysis showed this material is actually a mixture of several minerals, so it is technically a rock. The EDS analysis was corroborated by a thin section optical analysis. A mineralogist skilled in optical mineralogy independantly suggested the presence of rhodonite, a garnet mineral and a carbonate mineral. |
