PYROCHLORE Hurricane Mtn., Conway, NH About 3 mm FOV?	Species: PYROCHLORE Locality: Hurricane Mtn., Conway, NH Specimen Size: About 3 mm FOV? Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen and photo Notes: [bw] This is a greasy brown material. EDS analyses indicated a pyrochlore species. With no Ca or Na in the analysis, the fluorplumbopyrochlore species is suggested.
ZIRCON in Quartz crystal Hurricane Mtn., Conway, NH 2 mm zircon crystal embedded in a 1.5 cm quartz crystal ZIRCON in Quartz crystal Hurricane Mtn., Conway, NH 2 mm zircon crystal embedded in a quartz crystal	Species: ZIRCON in Quartz crystal Locality: Hurricane Mtn., Conway, NH Specimen Size: 2 mm zircon crystal embedded in a 1.5 cm quartz crystal Field Collected: Roger Eastman Catalog No.: A Don Dallaire specimen #4509 and photo Notes:
HEMATITE in Quartz crystal Quartz mine pocket, South Percy Peak, Stratford, NH 0.4 mm hexagonal hematite crystal embedded in quartz	Species: HEMATITE in Quartz crystal Locality: Quartz mine pocket, South Percy Peak, Stratford, NH Specimen Size: 0.4 mm hexagonal hematite crystal embedded in quartz Field Collected: Carlton Holt ~ 1986 Catalog No.: A Carlton Holt specimen, Don Dallaire photo Notes:
HEMATITE in Quartz crystal Quartz mine pocket, South Percy Peak, Stratford, NH 0.4 mm hexagonal hematite crystal embedded in quartz HEMATITE in Quartz crystal Quartz mine pocket, South Percy Peak, Stratford, NH 15 cm quartz crystal hosting hematite inclusions	Species: HEMATITE in Quartz crystal Locality: Quartz mine pocket, South Percy Peak, Stratford, NH Specimen Size: 0.4 mm hexagonal hematite crystal embedded in quartz, plus quartz crystal full view Field Collected: Carlton Holt ~ 1986 Catalog No.: A Carlton Holt specimen, Don Dallaire photo Notes:
GOYAZITE Palermo #1 Mine, Groton, NH 8 mm field of view. Oxide coated, cream interior, radial balls.	Species: GOYAZITE Locality: Palermo #1 Mine, Groton, NH Specimen Size: 8 mm field of view. Oxide coated, cream interior, radial balls. Field Collected: Forrest Fogg material Catalog No.: u2725 Notes: A 2024 Raman analysis by George Adleman (2/03/533) indicated goyazite. Surface coatings can be deceiving.
PYRRHOTITE Braemoor Rd., Salem, NH 3 mm field of view.	Species: PYRRHOTITE Locality: Braemoor Rd., Salem, NH Specimen Size: 3 mm field of view. Field Collected: Peter Cristofono - 2011 Catalog No.: u2730 Notes: Embedded hexagonal crystal.
ANATASE Wilton Crushed Stone Quarry, Wilton, NH 0.4 mm anatase crystal	Species: ANATASE Locality: Wilton Crushed Stone Quarry, Wilton, NH Specimen Size: 0.4 mm anatase crystal Field Collected: Peter DeVilliers - 2024 MMNE field trip. Catalog No.: A Peter DeVilliers specimen Notes:
FLUORITE Streeter Hill Fluorite locality, Chesterfield, NH 2.5 cm field of view	Species: FLUORITE Locality: Streeter Hill Fluorite locality, Chesterfield, NH Specimen Size: 2.5 cm field of view Field Collected: Don Swenson Catalog No.: A Don Swenson specimen Notes: The Streeter Hill fluorite occurrence is a Morrill locality. I [tm] visited this locality in April, 2006. The fluorite here is just milky. I only found massive cleavages, but Don found this specimen with some euhedral crystals in a quartz vug,
QUARTZ phantom with chlorite balls Streeter Hill Fluorite locality, Chesterfield, NH 6 mm field of view	Species: QUARTZ phantom with chlorite balls Locality: Streeter Hill Fluorite locality, Chesterfield, NH Specimen Size: 6 mm field of view Field Collected: Don Swenson Catalog No.: A Don Swenson specimen Notes: The Streeter Hill fluorite occurrence is a Morrill locality. Green chlorite balls delineating first generation quartz crystal growth.
PREHNITE Mine Falls Park locality, Nashua, NH 1.5 mm field of view	Species: PREHNITE Locality: Mine Falls Park locality, Nashua, NH Specimen Size: 1.5 mm field of view Field Collected: Tom Mortimer Catalog No.: u1326 Notes: I have had these specimens labeled as prehnite since I collected them in 1988. Viewing several recently posted (2024) mindat.org photos raised the possibility that these are the zeolite mineral clinoptilolite-Ca. Also present in this thin, waethered, calcite seam are tiny pyrite cubes, stilbite and quartz crystals - all very small. However a George Adleman Raman analyses indicated prehnite. Top five plot traces are from the specimen. The next two red traces are for the RUFF reference prehnite.
NATROLITE var. spreustein Red Hill, Moultonborough, NH 2.3 cm specimen NATROLITE var. spreustein Red Hill, Moultonborough, NH 2.3 cm specimen - LW UV lighting	Species: NATROLITE var. spreustein Locality: Red Hill, Moultonborough, NH Specimen Size: 2.3 cm specimen Field Collected: Tom Mortimer Catalog No.: u2735 Notes: Orangish area fluoresces white in SW UV. A George Adleman Raman analyses (top black trace) gave a very good match for natrolite, (second red trace). Peter Cristofono commented "In nepheline syenites, sodalite and nepheline sometimes alter to a white decomposition product called "hydronephelite" or "spreustein." Mindat.org calls spruestein fine-grained natrolite that replaces sodalite or nepheline, and hydronephelite a mixture of about 80% natrolite (with a little gibbsite, etc.). In Salem. MA, the white, altered sodalite is fairly common. It fluoresces a strong white under long-wave UV, strong yellow-white under mid-wave UV, and somewhat weaker green-white under short-wave UV."
NATROLITE var. spreustein Red Hill, Moultonborough, NH 1.9 cm specimen NATROLITE var. spreustein Red Hill, Moultonborough, NH 1.9 cm specimen - LW UV lighting	Species: NATROLITE var. spreustein Locality: Red Hill, Moultonborough, NH Specimen Size: 1.9 cm specimen Field Collected: Tom Mortimer Catalog No.: u2736 Notes: Another Natrolite var. spreustein specimen.
