Species: SCORZALITE 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. |

Species: SCORZALITE 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 |
Species: SCORZALITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.6 mm scorzalite crystal Field Collected: A Bob Wilken specimen & photo Catalog No.: PALScorzalite01AS Notes: |

Species: SCORZALITE ? 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. |
