SANIDINE Bugsmouth Hill. Newton, NH 1.7 mm field of view	Species: SANIDINE Locality: Bugsmouth Hill. Newton, NH Specimen Size: 1.7 mm field of view Field Collected: Tom Mortimer Catalog No.: u2098 Notes: Visual identification by Tom Mortimer. Vug in rhyolite makes sanidine the most likely species.
WARDITE Charles Davis Mine, N. Groton, NH 0.9 mm two crystal group	Species: WARDITE Locality: Charles Davis Mine, N. Groton, NH Specimen Size: 0.9 mm two crystal group Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen and photo Notes: Wardite is rare at the Charles Davis Mine. [tm] This is the only example I have seen.
LAUMONTITE Construction site, N. side Spit Brook Rd. Nashua, NH 9 mm field of view	Species: LAUMONTITE Locality: Construction site, N. side Spit Brook Rd. Nashua, NH Specimen Size: 9 mm field of view Field Collected: Scott Whittemore - 1988 Catalog No.: u18 Notes:
SPHALERITE with Quartz Shelburne Lead Mine, Shelburne, NH 8 mm field of view	Species: SPHALERITE with Quartz Locality: Shelburne Lead Mine, Shelburne, NH Specimen Size: 8 mm field of view Field Collected: Tom Mortimer - 6/25/99 Catalog No.: u381 Notes: A 19 image stack with Meiji EMZ-5TR.
PYRITE Morse Brook, East of Rt.116, Easton, NH 1 cm pyrite cube in 4.5 cm specimen	Species: PYRITE Locality: Morse Brook, East of Rt.116, Easton, NH Specimen Size: 1 cm pyrite cube in 4.5 cm specimen Field Collected: Tom Mortimer - May, 2008 Catalog No.: NC Notes:
PYRITE Morse Brook, East of Rt.116, Easton, NH 9 mm by 15 mm pyrite crystal in matrix	Species: PYRITE Locality: Morse Brook, East of Rt.116, Easton, NH Specimen Size: 9 mm by 15 mm pyrite crystal in matrix Field Collected: Tom Mortimer - May, 2008 Catalog No.: 1666 Notes: Pyrite crystals at this locality are quite brittle. It is difficult to collect complete ones.
QUARTZ Perhaps 50 yards south of Line Hill Rd., Dumbarton, NH 11 cm specimen with oxide coated quartz crystals.	Species: QUARTZ Locality: Perhaps 50 yards south of Line Hill Rd., Dumbarton, NH Specimen Size: 11 cm specimen with oxide coated quartz crystals. Field Collected: Tom Mortimer Catalog No.: NC Notes: I was guided to this large quartz outcrop by Vince Valade in June 2003. 1 mm nodules of hematite-goethite are present on some of the crystal faces. This is a representative specimen from this obscure locality. This was a very difficult ledge to work. Vince used a Ryobi power drill.
QUARTZ Moose Pocket, Albany, NH 8.5 cm x 5 cm specimen. QUARTZ Moose Pocket, Albany, NH 8.5 cm x 5 cm specimen.	Species: QUARTZ Locality: Moose Pocket, Albany, NH Specimen Size: 8.5 cm x 5 cm specimen. Front & back views Field Collected: Catalog No.: A Ray Meyers purchased specimen Notes: Fritz Moritz photos.
APATITE-(CaOH) Palermo Mine, N. Groton, NH 8 mm field of view. Jumble of Apatite-(CaOH) hexagonal tablets. APATITE-(CaOH) Palermo Mine, N. Groton, NH 3 mm field of view	Species: APATITE-(CaOH) Locality: Palermo Mine, N. Groton, NH Specimen Size: Top photo: 8 mm field of view. Lower photo 3 mm field of view. Field Collected: Dana Jewell - 2002 Catalog No.: u2163 Notes: A January 2018 polished grain EDS analysis from this specimen indicated the Hydroxylapatite species. No fluorine was detected at 0.677 KeV (between the C and O peaks). The carbon (C) response is due to the carbon coating.
COLLINSITE Palermo Mine, N. Groton, NH 4 mm field of view.	Species: COLLINSITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 4 mm field of view. Field Collected: Dana Jewell - April 1999 Catalog No.: u2112 Notes: Dana gave me this in October 2017. He had it labeled fairfieldite. As I have found Palermo fairfieldite to be very rare, I wanted an EDS confirmation. Two separate EDS grain analysis were done, two probings each. The BC253 analyses were grains on carbon tape, the BC234 analyses were polished grain. A moderate variation in chemistry was observed. The APFU's were calculated normalizing for two atoms of Ca. The oxygens were not grouped with P and H, as this cannot be determined by EDS. BC253a => Ca₂(Mg_0.6,Fe_0.4,Mn_0.13)P_2.87O_40.8 This was best analysis, count peak value = 1100. BC253 => Ca₂(Fe_1.22,Mn_0.42)P_2.04O_32.4 . Mg response seen in plot but was not quantified by software. Small Al, Si, K likely feldspar contaminant. Count peak value = 300. BC234 => Ca₂(Mg_0.48)P_3.15O_31.9 Peak count value = 297. A Fe response was on the plot, but not quantified. BC234a => Ca₂P_3.74O_48.3 . Mg & Fe responses seen in plot but were not quantified by software. Count peak value = 342. The Handbook of Mineralogy gives a collinsite analysis of Ca_1.92(Mg_0.78,Fe_0.34)_Σ=1.12P_1.95O_9.6 and the ideal chemistry as: Ca₂(Mg,Fe)(PO₄)₂ · 2H₂O
TITANITE Audley Quarry, Merrimack, NH 0.7 mm titanite crystal.	Species: TITANITE Locality: Audley Quarry, Merrimack, NH Specimen Size: 0.7 mm titanite crystal Field Collected: Tom Mortimer Catalog No.: u1058 Notes:
COLUMBITE Ham Brook - 1100 ft elevation, Albany, NH 0.4 mm star crystal on microcline	Species: COLUMBITE Locality: Ham Brook - 1100 ft elevation, Albany, NH Specimen Size: 0.4 mm star crystal on microcline Field Collected: Bob Janules - 1996 Catalog No.: A Bob Janules specimen Notes: These black stars were analyzed by SEM-EDS. Label indicates "SEM# GFHB001".
SODALITE with Nepheline Red Hill, Horne Farm Quarry, Moultonborough, NH 4.3 cm specimen. Daylight photo. SODALITE with Nepheline Red Hill, Horne Farm Quarry, Moultonborough, NH 4.3 cm specimen. SW UV photo.	Species: SODALITE with Nepheline Locality: Red Hill, Horne Farm Quarry, Moultonborough, NH Specimen Size: 4.3 cm specimen.
