ARFVEDSONITE - altered?   Hurricane Mtn, Conway, NH
5 mm field of view

Species:           ARFVEDSONITE - altered?
Locality:          Hurricane Mtn, Conway, NH
Specimen Size: 5 mm field of view
Field Collected: Found in large box of uncleaned, untrimmed, Hurricane Mtn. specimens collected by Leroy Grant of Albany, NH (deceased). Collected in the 1970's.
Catalog No.: 2107
Notes: Matrix is small crystals of microcline-albite. Some tiny clear quartz crystals are also present. I considered aegirine, however it has not been reported from Hurricane Mtn. I have not previously seen a similar green, bladed, species from Hurricane.
Philip Morrill (1960) reports "Acmite" = aegirine from Red Hill in Moultonboro. Janet Cares includes aegirine in her Vol. 65, no. 4, Rocks & Minerals NH species list (pg.298), likely using Morrill's reference. Finally, Morrill's source is likely T. R. Meyers New Hampshire Minerals and Mines 1941, pg. 30. I have never seen a NH aegerine. It is remarkable how these references propagate without a demonstrable specimen!
A January 2019 polished grain EDS analysis (BC313) indicated a chemistry of NaFe1.78Si4.45O0.65 , normalized for 1 Na, (or Na3Fe5.34Si13.35O1.95 normalized for 3 Na). The oxygen value is very low for any pyroxene or amphibole. Aegirine chemistry is NaFeSi2O6 .
Candidate species that are visually and chemically close include:
Arfvedsonite    NaNa2(Fe2+4Fe3+)Si8O22(OH)2 -> Na:Fe:Si = 3:5:8 -> 1:1.7:2.7
Wilkinsonite    Na4(Fe2+8Fe3+4)O4[Si12O36] -> Na:Fe:Si = 1:3:3
Howieite          Na(Fe2+,Fe3+,Al,Mg)12(Si6O17)2(O,OH)10 -> Na:Fe:Si = 1:12:12
A side-by-side EDS of Hurricane Arfvedsonite and this specimen would be helpful. The BC313 indicates Arfvedsonite is the "best fit". I [tm] have not seen the greenish color on arfvedsonite before.

GLAUCONITE ?   Government Pit, Albany, NH
5.5 cm specimen with soft, pale-green, glauconite on microcline and smoky quartz.

Species:           GLAUCONITE ?
Locality:          Government Pit, Albany, NH
Specimen Size: 5.5 cm specimen with soft, pale-green, glauconite on microcline and smoky quartz.
Field Collected: Leroy Grant - early 1970's
Catalog No.: 2108
Notes: A PXRD analysis of a sample from this specimen gave a mixed result. A moderately high PXRD score went to corrensite, a dark green, dull, waxy, earthy, magnesium dominant, sheet silicate. A quantitative EDS analysis, with light element detection for this government pit mineral is needed.
A Kerry Day qualitative EDS analysis of a similar Government Pit specimen (# 1289) indicated a K, Si, Fe, Al mineral. Glauconite chemistry is: (K,Na)(Fe+3,Al,Mg)2((Si,Al)4O10)(OH)2 .

TITANITE   Government Pit, Albany, NH
1 mm field of view.

Species:           TITANITE
Locality:          Government Pit, Albany, NH
Specimen Size: 1 mm field of view.
Field Collected: Leroy Grant - early 1970's
Catalog No.: Locate ??
Notes: EDS verified, set 23 - but no file saved. [tm] I did not suspect these small, tan, waxy, crystals were titanite.

BERYL   Ledge Pond Mica Mine, Sunapee, NH.
3.4 cm double terminated crystal

Species:           BERYL
Locality:          Ledge Pond Mica Mine, Sunapee, NH.
Specimen Size: 3.4 cm double terminated crystal
Field Collected: Harold Post - NH collector
Catalog No.: 2109
Notes: Found these double terminated 3.4 cm (1 -3/4 inch) beryl crystals in a cigar box at Gilsum Show - 2109. Locality labeled in box: Ledge Pond Mica Mine, Sunapee, NH. From a deceased collector - Harold Post (western NH home).
Price - one dollar each! Terminated beryl crystals are quite uncommon in NH, so was happy to get these. I have never visited this locality.... or seen specimens from it previously.... but it is listed in Morrill's book.

SYNCHYSITE-(Ce) with blue anatase   Audley Quarry, Merrimack, NH
2.5 mm Field of View

Species:           SYNCHYSITE-(Ce) with blue anatase
Locality:          Audley Quarry, Merrimack, NH
Specimen Size: 2.5 mm Field of View
Field Collected: Tom Mortimer 2019
Catalog No.: u2242
Notes: There are a few smaller synchysite crystals on the specimen. Only one like this I found. I am calling this synchysite-Ce, by similarity to the analyzed Mine Falls Park synchysite-Ce. The host rock at MFP is same as at Audley, and only three miles distant.

SYNCHYSITE-(Ce)    Audley Quarry, Merrimack, NH
0.3 mm synchysite crystal

Species:           SYNCHYSITE-(Ce)
Locality:          Audley Quarry, Merrimack, NH
Specimen Size: 0.3 mm synchysite crystal
Field Collected: Tom Mortimer 2019
Catalog No.: u2242
Notes: There are a few smaller synchysite crystals on the specimen. This one is second largest, split down the "C" axis.

BROOKITE    Audley Quarry, Merrimack, NH
About a 0.1 mm brookite crystal

Species:           BROOKITE
Locality:          Audley Quarry, Merrimack, NH
Specimen Size: About a 0.1 mm brookite crystal
Field Collected: Tom Mortimer 2019
Catalog No.: u2243
Notes: There are several tiny brookite crystals on this specimen. Some are a bit larger, but this one has terminated edges all around. This photo is at the highest magnification of my equipment. The photo shows details I cannot see with my Meiji stereo scope.
