Locality:          Chickering Mine, Walpole, NH
Specimen Size: 6 cm specimen with triphylite (blue), heterosite (purple) and ferrisicklerite (brown)

TRIPHYLITE    Chickering Mine, Walpole, NH
8 cm massive blue triphylite specimen with included mica

Species:           TRIPHYLITE
Locality:          Chickering Mine, Walpole, NH
Specimen Size: 8 cm massive blue triphylite specimen with included mica
Field Collected: Tom Mortimer   (Oct. 2010)
Catalog No.:
Notes: Triphylite is the predominant primary phosphate at the Chickering Mine. The blue triphylite on the freshly broken surface sharply contrasts with the surface exposed to years of weathering on the mine dump. The brown zone in the top right has altered to ferrisicklerite.

TRIPHYLITE    Ruggles Mine, Grafton, NH
4.7 cm specimen

TRIPHYLITE    Ruggles Mine, Grafton, NH
2 cm zoom view


Species:           TRIPHYLITE  
Locality:          Ruggles Mine, Grafton, NH
Specimen Size: 4.7 cm specimen with 1.2 cm triphylite crystal, top. Zoom view is 2 cm.
Field Collected: Purchased specimen from D. Robenson Minerals.    Ex. Johanson collection - 1942
Catalog No.: 1876
Notes: Phillip Morrill does report triphylite as occurring at the Ruggles Mine. Triphylite crystals have scaly flakes of fluorescent autunite on their surface. Uranium minerals such as autunite are common at the Ruggles Mine.
Specimen contains many broken triphylite crystals, but only one essentially complete one.

TRIPHYLITE    Parker Mtn. Mine, Center Strafford, NH
8 cm specimen. 4 cm triphylite-lithiophylite zone with rind of ferrisicklerite and heterosite
Species:           TRIPHYLITE   LiFe2+PO4
Locality:          Parker Mtn. Mine, Center Strafford, NH
Specimen Size: 8 cm specimen. 4 cm triphylite-lithiophylite zone with rind of ferrisicklerite and heterosite
Field Collected: Ron Bonney, purchased in 1982 by Gene Bearss
Catalog No.:
Notes: This "triphylite" has a more greener shade than most NH triphylite. An EDS analysis shows Mn and Fe content about equal. The EDS analyst opined that it was "slightly Mn dominant" so slightly on the lithiophylite side of the series.

Notes: This is the only Parker Mtn. Mine tryphylite crystal the author has seen.

TRIPHYLITE    Valencia Mine, N. Groton, NH
6.5 cm specimen of massive triphylite.
Species:           TRIPHYLITE  
Locality:          Valencia Mine, N. Groton, NH
Specimen Size: 6.5 cm specimen of massive triphylite
Field Collected: Dana Jewell
Catalog No.: NC
Notes: A voucher specimen for un-altered triphylite at the Valencia Mine

TRIPHYLITE    EE Smith Mine, Alexandria, NH
A 6 cm chunk of massive triphylite.
Species:           TRIPHYLITE  
Locality:          EE Smith Mine, Alexandria, NH
Specimen Size: A 6 cm chunk of massive triphylite.
Field Collected: Tom Mortimer
Catalog No.: NC
Notes: A voucher specimen for triphylite at the EE Smith Mine, Alexandria, NH. This triphylite has a more brownish tint than some other NH triphylite occurrences.

4 mm pale-blue triphylite crystal

TRIPHYLITE    Chandlers Mill Mine, Newport, NH
6 mm pale-blue triphylite crystal


Highslide JS
TRIPHYLITE    Chandlers Mill Mine, Newport, NH
4 mm pale-blue triphylite crystal
Species:           TRIPHYLITE  
Locality:          Chandlers Mill Mine, Newport, NH
Specimen Size: 4 to 6 mm pale-blue triphylite crystals
Field Collected: Unknown
Catalog No.: u1816, u1817, u1818
Notes: I purchased a golf ball sized Chandlers Mill specimen from Ted Johnson (Yankee Minerals) at the 2015 Springfield, MA show that contained numerous 1 to 6 mm triphylite crystals. Most were broken, but I thought I might find a few mostly complete ones if I broke up the specimen. The Chandlers Mill Mine is a world class occurrence for triphylite crystals. The largest ones can approach one inch in size and can sell for many hundreds of dollars. I paid $10 for this specimen.

TRIPHYLITE    G.F. Smith Mine, Newport, NH
4.5 cm specimen with dark blue massive triphylite and feldspar
Species:           TRIPHYLITE   
Locality:          G.F. Smith Mine, Newport, NH
Specimen Size: 4.5 cm specimen with dark blue massive triphylite and feldspar
Field Collected: Tom Mortimer
Catalog No.: 2025
Notes: A voucher specimen for tyriphylite at the G. F. Smith Mine. Note: The G. F. Smith Mine is to the north of Chandlers Mill Rd., between Chandlers Mill Rd. and the Sugar River. The more famous Chandlers Mill Mine is on the south side of Chandlers Mill road.

TRIPHYLITE - altered   Valencia Mine, N. Groton, NH
2.5 cm specimen with 1.5 cm altered triphylite crystal

Species:           TRIPHYLITE - altered crystal
Locality:         Valencia Mine, N. Groton, NH
Specimen Size: 2.5 cm specimen with 1.5 cm altered triphylite crystal
Field Collected: Tom Mortimer
Catalog No.: 1608
Notes: Triphylite is likely altered to mostly ferrisicklerite, but visible small cavities have other alteration products. The yellow mineral may be stewartite. The Valencia Mine is the only NH locality where I have seen euhedral altered triphylite crystals with visible micro phosphates included.
The Chandlers Mill Mine in Newport, NH has produced the "worlds best" triphylite crystals, but all examples from this locality are un-altered. I acknowledge the Palermo Mine in N. Groton has huge altered triphylite crystals, but most of these altered single crystals would fill the bed of a pick-up truck.
