Field Collected: Tom Mortimer
Catalog No.:
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 2.5 mm palermoite crystal - two views
Field Collected: From crate of Palermo rocks given by Bob Whitmore
Catalog No.: u1248
Notes: Associations include jackstraw strunzite and rockbridgeite over-growth on termination.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 2 mm fov
Field Collected: Walter Lane - from material purchased by the Micromounters of New England
Catalog No.: u1250
Notes: Shows orthorhombic termination nicely.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: Group of 2 mm prismatic palermoite crystals
Field Collected: ex Mike Swanson collection
Catalog No.: u927
Notes: Lateral crystal in lower left is also palermoite.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 4 mm Palermoite crystal on quartz, two views
Field Collected: Bob Whitmore - 1974
Catalog No.: A Bob Whitmore specimen
Notes: Bob Whitmore had this specimen labeled as samuelsonite. An EDS analysis (2013) showed a large strontium content (@ ~ 1.8 KeV) indicating the species is palermoite, not samuelsonite. Samuelsonite and palermoite are frequently confused.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: Vertical crystal with stippled termination is 1.7 mm
Field Collected: Walter Lane material
Catalog No.: A Bob Janules specimen
Notes: Palermoite confirmed by EDS analysis
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3 mm and 2 mm fields of view
Field Collected: From a phosphate rock saved by Forrest Fogg, acquired by Gordon Jackson and passed along to Bob Wilken.
Catalog No.: A Bob Wilken specimen
Notes: Bob originally had visually ID'ed this as parascholzite, but a carbon tape mounted grain EDS analysis indicated a reasonably good fit for palermoite, with an APFU calculated from this analysis as:
Na1.87Sr0.23Fe0.29Al4(PO4)3.67(OH)15.6 normalized for four Al.
Palermoite chemistry is: (Li,Na)2SrAl4(PO4)4(OH)4 . EDS cannot detect lithium.
The strontium content indicated by the analysis for this Bob Wilken specimen is quite low and some Fe was present, perhaps due to surface contamination. The Na, Al and P values are quite close to those for palermoite.
