MAGNETITE Soapstone Quarry, Richmond, NH 4 cm specimen with magnetite zones to 1.2 cm in quartz-feldspar matrix.	Species: MAGNETITE Locality: Soapstone Quarry, Richmond, NH Specimen Size: 4 cm specimen with magnetite zones to 1.2 cm in quartz-feldspar matrix. Field Collected: Tom Mortimer - 2006 Catalog No.: 1871 Notes: Magnetite identification by strong magnetic attraction. Magnetite has not appeared on previous Richmond Soapstone Quarry species lists.
MAGNETITE in muscovite Parker Mtn. Mine, Center Strafford, NH 2.5 mm field of view – magnetite? embedded in muscovite	Species: MAGNETITE in muscovite Locality: Parker Mtn. Mine, Center Strafford, NH Specimen Size: 2.5 mm field of view – magnetite? embedded in muscovite Field Collected: Dana Morong Catalog No.: A Dana Morong specimen Notes: Specimen is illuminated from the rear. An illustration of magnetite inclusions in muscovite from an American Mineralogist article by Frondel & Ashby, vol. 22 (1937) pg. 106 compares very favorably to this Parker Mtn. specimen.
MAGNETITE in QUARTZ Gale River, Franconia, NH 1.4 cm specimen	Species: MAGNETITE in Quartz Locality: Gale River, Franconia, NH Specimen Size: 1.4 cm specimen Field Collected: Joey Vaughan Catalog No.: 2023 Notes: The first EDS analysis suggested fayalite, the iron end member of the olivine group. Microscope examination of the specimen showed both dark glassy grains and clear glassy grains. Both the dark and clear grains were magnetic. A follow-up EDS analysis of the dark grains showed only Fe and O present, indicating magnetite. An analysis of a clear grain showed it to be just quartz. At highest magnification, the "clear" grains were observed to have tiny black inclusions, very likely magnetite. These magnetite inclusions gave the clear grains their magnetic attraction. The first analysis suggesting fayalite must have included an area of both magnetite and quartz. An acknowledgement to Peter Cristofono who noticed the tiny black inclusions in the clear grains.
MAGNETITE Ellacoya Locale, Gilford, NH 0.8 mm magnetite crystal	Species: MAGNETITE Locality: Ellacoya Locale, Gilford, NH Specimen Size: 0.8 mm magnetite crystal Field Collected: Bob Janules Catalog No.: A Bob Janules specimen Notes:
