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.
