Locality: Charles Davis Mine, N. Groton, NH
Specimen Size: Full view of specimen 1305. A 3 cm specimen.
Field Collected: Redge Webster
Catalog No.: 1305
Notes:
Locality: Jackson Hill, Stoddard, NH
Specimen Size: 3 cm zone of massive scorzalite with muscovite mica
Field Collected: A Harvard Mineral Museum specimen
Catalog No.: #100715 Labeled as Lazulite
Notes: A Feb., 2011 EDS analysis of a grain from this specimen showed an absence of magnesium indicating this phosphate species is scorzalite, Fe2+Al2(PO4)2(OH)2 , not lazulite, (Mg,Fe2+)Al2(PO4)2(OH)2 . Kerry opined that this is scorzalite, by the strong Fe response. The Kerry Day instrument has poor light element response below 1.0 KeV. The Mg line would be at 1.25 KeV. Although the instrument response is low in this area, if Mg were greater than Fe, it would have registered, per Kerry Day.

Specimen Size: 1.2 mm scorzalite crystal
Field Collected: Janet Cares ? (ex. Janet Cares specimen)
Catalog No.: u2296
Notes: A scorzalite crystal on u2296.
Locality: Palermo #2 Mine, N. Groton, NH
Specimen Size: 5 mm field of view
Field Collected: Jim Nizamoff
Catalog No.: A Jim Nizamoff specimen and photo
Notes: Scorzalite crystals are rare at the Palermo Mines. Massive scorzalite is common.
Jim Nizamoff forwarded two analyses from Palermo #2 lazulite-scorzalite series specimens.
[tm] I have neglected tiny bits of Ca, Na, Mn, Ti, F reported in Jim's analyses.
Lazulite: (Fe0.349,Mg0.629)Al2.019(PO4)2.0(OH)2.0
Scorzalite: (Fe0.732,Mg0.211)Al2.069(PO4)2.0(OH)2.0
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.6 mm scorzalite crystal
Field Collected: A Bob Wilken specimen & photo
Catalog No.: PALScorzalite01AS
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3.2 mm field of view. Very dark blue scorzalite crystal cluster.
Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob.
Catalog No.: u2429
Notes: If not scorzalite, another possibility is cornetite, a copper phosphate. Some mindat.org photos of cornetite are a fair visual fit for these crystals. The host rock sample for these micros had a fair amount of chalcopyrite, a possible source for the copper.
