Locality: N. Sugarloaf Mtn., Bethlehem, NH
Specimen Size: 1.2 mm prismatic zircon crystal cluster in albite vug.
Field Collected: Tom Mortimer
Catalog No.: u172
Notes: This group was quite deep within the vug, so difficult to get a lot of light onto it. Most of the prismatic zircon crystals at the N. Sugarloaf locality are embedded in feldspar. Free-standing zircon crystals are uncommon. The yellow crusty mineral on the zircon is likely mica. This zircon group is not fluorescent.
Locality: Knox Mtn., Ossipee, NH
Specimen Size: 1.0 mm zircon crystal
Field Collected: Tom Mortimer
Catalog No.: u264
Notes:
Locality: Parker Mtn. Mine, Strafford, NH
Specimen Size 5 cm field of view - three views
Field Collected: Fred Davis - 2018
Catalog No.: A Fred Davis specimen and photo
Notes:
Locality: Parker Mtn. Mine, Strafford, NH
Specimen Size Detail view in white light and SW UV of odd crust on bottom side. Looks like quartz in areas that don't fluoresce, and something with lots of uranyl ions elsewhere.
Field Collected: Fred Davis - 2018
Catalog No.: A Fred Davis specimen and photo
Notes: [tm] Perhaps a hyalite coating?
Locality: N. Sugarloaf Mtn., Bethlehem, NH
Specimen Size: 11 mm field of view. Acicular red-brown zircon in feldspar.
Field Collected: Tom Mortimer
Catalog No.: u2174
Notes: A polished grain EDS analysis (BC276) confirmed zircon, with a trace of uranium. This specimen was the source for the EDS analysis.
Locality: Hurricane Mtn, Conway, NH
Specimen Size: 3.5 mm crystal
Field Collected: Tom Mortimer
Catalog No.: Not Cataloged
Notes: These Hurricane Mtn. zircons have only a very pale yellow fluorescence in SW UV.

Specimen Size: 3 mm field of view
Field Collected: Tom Mortimer - 8/19
Catalog No.: u2261
Notes: Smaller, crude octahedron, zircon crystal in lower left. These zircons are not fluorescent.
