HYDROXYLHERDERITE ? Chickering Mine, Walpole, NH 4 mm fov. "Fish egg" herderite?	Species: HYDROXYLHERDERITE ? Locality: Chickering Mine, Walpole, NH Specimen Size: 4 mm fov. "Fish egg" herderite? Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen Notes: A similar appearing mineral form has been seen at both the Chickering Mine, Walpole, NH and at Palermo Mine in N. Groton, NH. The Palermo sample was analyzed to be siderite. An EDS analysis, suggested the best fit for this Chickering mineral to be hydroxylherderite. No fluorine was detected in the analysis. The green spray is likely greifensteinite.
MARCASITE with Vivianite Keyes Mine, Orange, NH 1.2 mm marcasite crystal with small tabular vivianite crystal	Species: MARCASITE with Vivianite Locality: Keyes Mine, Orange, NH Specimen Size: 1.2 mm marcasite crystal with small tabular vivianite crystal Field Collected: Clayton Ford. Acquired by Gordon Jackson 2003. Gifted to Tom Mortimer 9/16 Catalog No.: u1999 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. Photo from a 47 image stack processed with Helicon Focus.
PSEUDOLAUEITE Palermo Mine, N. Groton, NH 0.2 mm pseudolaueite crystal	Species: PSEUDOLAUEITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.2 mm pseudolaueite crystal Field Collected: Catalog No.: An Arnaldo Brunetti collection specimen Notes: This 0.2 mm crystal is at the limit of what I can photograph.
MUSCOVITE with tabular apatite Palermo Mine, N. Groton, NH 4 mm crystal group	Species: MUSCOVITE with tabular apatite Locality: Palermo Mine, N. Groton, NH Specimen Size: 4 mm crystal group Field Collected: Clayton Ford. Gift from Gordon Jackson Catalog No.: u2007 Notes:
MONTEBRASITE Palermo Mine, N. Groton, NH 10 mm field of view. Triclinic, truncated, pyramids of grayish montebrasite.	Species: MONTEBRASITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 10 mm field of view. Triclinic, truncated, pyramids of grayish montebrasite. Field Collected: Clayton Ford, A gift from Gordon Jackson Catalog No.: u2011 Notes: A polished grain EDS analysis (BC139) indicated an aluminum phosphate, (EDS carbon response is due to carbon coat). Chemistry and crystalography are a better fit for montebrasite LiAlPO₄(OH,F) than for augelite, the other Al-P candidate. The white spiky clusters are believed to be type 3 goyazite.
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.: TBC 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 !
GOETHITE Stoddard Mine, Westmoreland, NH 9 mm field of view. Dark brown, resinous, goethite in quartz with green malachite	Species: GOETHITE Locality: Stoddard Mine, Westmoreland, NH Specimen Size: 9 mm field of view. Dark brown, resinous, goethite in quartz with green malachite Field Collected: Tom Mortimer Catalog No.: TBC Notes: Goethite confirmed by EDS analysis (BC136). For some time I had wondered what this brown resinous mineral was. The analysis and surrounding malachite indicate a former chalcopyrite mineral altered to goethite.
HEULANDITE Merrimack Inustrial Interchange road cut, Merrimack, NH 9 mm field of view.	Species: HEULANDITE Locality: Merrimack Inustrial Interchange road cut, Merrimack, NH Specimen Size: 9 mm field of view. Field Collected: Tom Mortimer Catalog No.: A Gordon Jackson specimen Notes: I traded this TN specimen to Vince Valade years ago. Gordon has acquired Vince's TN collection. Stilbite, chabazite, and heulandite zeolite species were found (1989, 1990) in a thin rock seam adjacent to a basalt dike that was exposed in the massive road cut for the Merrimack Industrial Interchange. (F. E. Everett Turnpike Exit 10). The zeolites from this locality had a brown resinous coating when collected.
PYROMORPHITE Madison Lead Mine, Madison, NH 1.5 mm Pyromorphite cluster	Species: PYROMORPHITE Locality: Madison Lead Mine, Madison, NH Specimen Size: 1.5 mm Pyromorphite cluster Field Collected: Bob Janules Catalog No.: An Anna Wilken specimen Notes:
WULFENITE Madison Lead Mine, Madison, NH 0.3 mm wulfenite crystal	Species: WULFENITE Locality: Madison Lead Mine, Madison, NH Specimen Size: 0.3 mm wulfenite crystal Field Collected: Bob Janules Catalog No.: An Anna Wilken specimen Notes: Wulfenite at the Madison Lead Mine is rare and tiny.
HELVITE Madison Lead Mine, Madison, NH Helvite crystals to 0.5 mm.	Species: HELVITE Locality: Madison Lead Mine, Madison, NH Specimen Size: Helvite crystals to 0.5 mm. Field Collected: Anna Wilken Catalog No.: An Anna Wilken specimen Notes: [tm] This is the first Madison Lead Mine helvite I have seen.
CRANDALLITE Palermo Mine, N. Groton, NH 0.5 mm crandallite ball CRANDALLITE Palermo Mine, N. Groton, NH 0.5 mm white crandallite balls	Species: CRANDALLITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.5 mm crandallite ball. Second photo shows two on specimen. Field Collected: Forrest Fogg Catalog No.: An Bob Wilken specimen and photos Notes: A semi-quantative polished grain analysis of sample from this specimen indicated a chemistry: CaBa_0.1Al_4.1P_2.9O₁₀ (normalized for one Ca and rounded to nearest 0.1 APFU.) Crandallite chemistry is: CaAl₃(PO₄)(PO₃OH)(OH)₆ Note, EDS cannot detect H. Crandallite is the closest fit available for the EDS indicated chemistry, but still not a particularly good match. Dana's System of Mineralogy indicates "Ba, Sr and rare earths may substitute for Ca" in crandallite.
