PHOSPHOSIDERITE    Palermo #1 Mine, N. Groton, NH
~ 1 mm? pink phosphosiderite crystal
Species:           PHOSPHOSIDERITE   Fe3+PO4·2H2O
Locality:          Palermo #1 Mine, N. Groton, NH

Specimen Size: ~ 1 mm? pink phosphosiderite crystal
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen
Notes: Phosphosiderite and strengite are dimorphs. Strengite is orthorhombic, phosphosiderite is monoclinic. Phosphosiderite is more common in the Fletcher and Valencia Mines, (also in N. Groton), as brilliant purple aggregates of botryoidal crystals. Bob Whitmore's book The Pegmatite Mines Known as Palermo shows phosphosiderite only in the botryoidal form from Palermo. There is no mention of phosphosiderite occuring in discrete xl form such as these, whereas the strengite is illustrated in form like this. When Bob Whitmore examined this specimen, he thought phosphosiderite was the appropriate ID.

Species:           PHOSPHOSIDERITE
Locality:          Valencia Mine, Groton, NH
Specimen Size: 2.5 cm specimen. George Adleman full specimen photo.
Field Collected: Tom Mortimer
Catalog No.: Gifted to George Adleman
Notes: A micro crystaline crust of brown coated square plates of phosphosiderite. The plates are clear beneath the well bonded brown crust. The black matrix is rockbridgeite.
A George Adleman Raman spectrum , Raman spectrum2 was an excellent match for phosphosiderite.
