SIDERITE Palermo Mine, N. Groton, NH Rhombic, oxide coated siderite crystals to 5 mm	Locality: Palermo Mine, N. Groton, NH Specimen Size: Rhombic, oxide coated siderite crystals to 5 mm Field Collected: Tom Mortimer Catalog No.: 175 Notes:
SIDERITE Keyes #1 Mine, Orange, NH 5 mm field of view. Scallop shell-shaped, orange, siderite crystals.	Locality: Keyes #1 Mine, Orange, NH Specimen Size: 5 mm field of view. Scallop shell-shaped, orange, siderite crystals. Field Collected: Tom Mortimer Catalog No.: u170 Notes: This Keyes Mine siderite was confirmed by EDS analysis. The plot shows a strong Fe response with minor Mn and Mg. Light elements O and C are outside the instrument's range. An quantitative analysis of a similar Peter Cristofono specimen (NH54, BC set 28, May, 2021) indicated a magnesium rich siderite with about 28% magnesium and 8% manganese replacing iron in the siderite composition. The varietal name "sideroplesite" has been used for Mg rich siderite. Reference Dana's System of Mineralogy, vol. II, 7th edition, pg. 169.
