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. |

Species: PHOSPHOSIDERITE Locality: Valencia Mine, Groton, NH Specimen Size: 8 mm field of view Field Collected: Tom Mortimer Catalog No.: u2510 Notes: A micro crystaline crust of flat tabular plates of phosphosiderite on rockbridgeite botryoids. A George Adleman Raman spectrum was an excellent match for phosphosiderite. |

Species: PHOSPHOSIDERITE Locality: Palermo Mine, Groton, NH Specimen Size: 0.48 mm crystal Field Collected: Bob Wilken Catalog No.: A Bob Wilken collection specimen Notes: [bw] This one has "a truer approximation of the color. A combo photo of a phosphosiderite xl with rockbridgeite and hureaulite xls. I attempted this two times. The first time with the ping-pong balls on the lights, the second with the specimen within (in this case under due to specimen size) the larger pp ball. The first way resulted in having too much flaring within the crystals as well as on the rockbridgeite. I attempted a fair amount of cloning to blot it out but lost other quality in the process so I ditched it. The second time I tried adjusting the lighting to avoid any potential internal flaring but still got overexposure on the hureaulite xl to the left. With so many of these reflective light colored xls being very transparent there's always something that creates a lighting problem. A stack of 115 and 6 um increments." |
