HAGENDORFITE Palermo Mine, N. Groton, NH 2.5 mm green-black stubby-prismatic hagendorfite crystal in ludlamite	Species: HAGENDORFITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 2.5 mm green-black stubby-prismatic hagendorfite crystal in ludlamite Field Collected: Walter Lane, gift from Bob Janules Catalog No.: u1249 Notes: The EDS analysis suggested "ferroalluaudite" (the analyist's suggestion). The Na response in the plot is greatly attenuated by the EDS instrument. Hagendorfite is a member of the alluaudite group of minerals. Hagendorfite is listed for the Palermo Mine, so that is the species assigned to this crystal.
HAGENDORFITE Palermo Mine N. Groton, NH 0.6 mm dark-green hagendorfite crystal in pale-green ludlamite	Species: HAGENDORFITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.6 mm dark-green hagendorfite crystal in pale-green ludlamite Field Collected: ex. Bill Henderson Catalog No.: A Joe Mulvey specimen, ex. Bill Henderson Notes:
HAGENDORFITE Palermo Mine, N. Groton, NH 1 mm hagendorfite crystal in ludlamite vug	Species: HAGENDORFITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1 mm hagendorfite crystal in ludlamite vug Field Collected: Clayton Ford. Acquired by Gordon Jackson 2003. Gifted to Tom Mortimer 9/16 Catalog No.: u2000 Notes: Most hagendorfite crystals are found embedded in ludlamite. This one was free-formed in a ludlamite vug.

HAGENDORFITE - Alluaudite series Palermo Mine, N. Groton, NH 6 mm crystal with partial mitriditite coating HAGENDORFITE - Alluaudite series Palermo Mine, N. Groton, NH 4 mm crystal	Species: HAGENDORFITE - Alluaudite series Locality: Palermo Mine, N. Groton, NH Specimen Size: Top photo: 6 mm crystal with partial mitriditite coating. Bottom photo: 4 mm crystal. Matrix is messelite-fairfieldite. Field Collected: Clayton Ford. Gift from Gordon jackson Catalog No.: u2024 Notes: Two polished grain analyses (BC137) were done. The first EDS analysis showed ample sodium and small amounts of several metalic elements (Ca, Fe, K, Mn). The second probed point EDS analysis lacked these low concentrations and showed no sodium, so some zone growth is likely present. Previously seen Palermo hagendorfite crystals have been embedded in ludlamite, (e.g. # u2000), so these are different in that respect. Point 1 chemistry (normalized for 3 P): Na_2.55Mg_0.64Al_0.47Ca_0.24K_0.27Mn_0.2Fe_0.37P₃O₃₂ Point 2 chemistry (normalized for 3 P): Mg_0.78Al_0.48Fe_0.13P₃O_30.9 Hagendorfite chemistry is: NaCaMn²⁺Fe²⁺₂(PO₄)₃ The most sodium rich member of the alluaudite group is Ferroalluaudite- (Na Na): Na₄Na₄Fe²⁺₄Fe³⁺₈(PO₄)₁₂ There is a lot of element variation within the allauadite series !
HAGENDORFITE Palermo #1 Mine, Groton, NH 3.5 mm field of view	Species: HAGENDORFITE Locality: Palermo #1 Mine, Groton, NH Specimen Size: 3.5 mm field of view Field Collected: Don Dallaire Catalog No.: Don Dallaire specimen #3995 Notes: I found only two complete crystals on the specimen. The first was in a cluster of others. Not much contrast, as I had to brightly illuminate to get much definition, so appears a bit washed out.
