PYROMORPHITE Johnson Rd. Locale, Bow, NH 1.1 mm field of view PYROMORPHITE Johnson Rd. Locale, Bow, NH zoom view PYROMORPHITE Johnson Rd. Locale, Bow, NH 1.7 mm field of view	Species: PYROMORPHITE Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 1.1 mm field of view - top photo Field Collected: Paul Young - 2016 Catalog No.: A Bob Wilken specimen and photos Notes: A Bob Wilken visual ID. Clear pyromorphite is rare. No photos of clear pyromorphite are on mindat.org - 2022.
PYROMORPHITE Johnson Rd. Locale, Bow, NH 1.0 mm field of view	Species: PYROMORPHITE Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 1.0 mm field of view Field Collected: Paul Young - 2016 Catalog No.: Anna Wilken specimen. Bob Wilken photo Notes:
WULFENITE Johnson Rd. Locale, Bow, NH 0.9 mm vertical crystal	Species: WULFENITE Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 0.9 mm vertical crystal Field Collected: Paul Young - 2016 Catalog No.: Anna Wilken specimen. Bob Wilken photo Notes: An Anna and Bob Wilken ID.
COVELLITE Johnson Rd. Locale, Bow, NH 0.8 mm field of view	Species: COVELLITE Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 0.8 mm field of view Field Collected: Paul Young - 2016 Catalog No.: Bob Wilken specimen and photo Notes: Similar to a previously analyzed Cu,S,Zn Johnson Rd. specimen that suggested covellite as a "best fit", but not particularly well.
COLUMBITE-Mn Turner Mine, Marlow, NH 10.5 mm crystal	Species: COLUMBITE-Mn Locality: Turner Mine, Marlow, NH Specimen Size: 10.5 mm crystal Field Collected: Bob Wilken Catalog No.: Bob Wilken specimen and photo Notes: A polished grain weight% oxide EDS analysis, normalized for 6 oxygen, gave Nb_0.75Ta_0.38Mn_2.61Fe_0.54O₆ . [tm] With Nb >> Ta, this indicates Columbite-Mn.
MITRIDATITE Palermo Mine, Groton, NH 6.8 mm field of view	Species: MITRIDATITE Locality: Palermo Mine, Groton, NH Specimen Size: 6.8 mm field of view Field Collected: Bob Wilken Catalog No.: Bob Wilken specimen and photo Notes: An EDS analysis, normalized for 4 Fe, gave Ca_1.51Fe_4.0P_2.14O_16.5. The material tested was the concentrically-ringed greenish-brown mineral. Bob gave consideration to a dufrenite ID. Dufrenite chemistry is: Ca_0.5Fe²⁺Fe³⁺₅(PO₄)₄(OH)₆ · 2H₂O . The analysis of this specimen is a poor fit for dufrenite. The best IMA match is mitridatite.
MESSELITE Palermo Mine, Groton, NH 11 mm field of view MESSELITE Palermo Mine, Groton, NH 8 mm field of view	Species: MESSELITE Locality: Palermo Mine, Groton, NH Specimen Size: 11 mm field of view and 8 mm close-up. Field Collected: A Janet and Steve Cares - 1977 Catalog No.: A Don Dallaire specimen and photo Notes: Acquired by Don at a 2022 MMNE auction.
BASTNASITE Hurricane Mtn., Conway, NH 0.5 mm crystal	Species: BASTNASITE Locality: Hurricane Mtn., Conway, NH Specimen Size: 0.5 mm crystal Field Collected: Bob Wilken Catalog No.: Bob Wilken specimen and photo Notes: Bob Wilken ID
BASTNASITE embedded in arfvedsonite Hurricane Mtn., Conway, NH Largest crystal is 1.1 mm	Species: BASTNASITE embedded in arfvedsonite. Locality: Hurricane Mtn., Conway, NH Specimen Size: Largest crystal is 1.1 mm Field Collected: Bob Wilken Catalog No.: Bob Wilken specimen and photo Notes: [BW} "I find this one rather interesting and consider it to be more primary to the emplacement of the various species. Most of the free-standing ones seem to be secondary and are usually half this size."
COLUMBITE-Mn Government Pit, Albany, NH 1.2 mm Columbite-Mn crystal	Species: COLUMBITE-Mn Locality: Government Pit, Albany, NH Specimen Size: 1.2 mm Columbite-Mn crystal Field Collected: Gene Bearss Catalog No.: Gene Bearss # 1982C. Now with the MMGM collection #2014.142.5454 Notes: This is a redo of a 2015 photo from a batch of micros that Gene loaned me to photo. Gene's micro collection was acquired by the Maine Mineralogical and Gem Museum. The museum loaned me this specimen to re-photo.
