HYDROXYLHERDERITE Fletcher Mine, Groton, NH 1.4 cm crystal	Species: HYDROXYLHERDERITE Locality: Fletcher Mine, Groton, NH Specimen Size: 1.4 cm crystal Field Collected: Ralph Lingard Catalog No.: A Bob Janules specimen and photo Notes: [bj] These were collected by Ralph Lingard many years ago. He gave them to me. I recalled he had a lot of them in a glass jar.
HYDROXYLHERDERITE Fletcher Mine, Groton, NH 1.5 cm crystal	Species: HYDROXYLHERDERITE Locality: Fletcher Mine, Groton, NH Specimen Size: 1.5 cm crystal Field Collected: Ralph Lingard Catalog No.: A Bob Janules specimen and photo Notes: [bj] These were collected by Ralph Lingard many years ago. He gave them to me. I recalled he had a lot of them in a glass jar.
HYDROXYLHERDERITE Fletcher Mine, Groton, NH 1.4 cm and 1.5 cm crystals	Species: HYDROXYLHERDERITE Locality: Fletcher Mine, Groton, NH Specimen Size: 1.4 cm and 1.5 cm crystals Field Collected: Ralph Lingard Catalog No.: A Bob Janules specimen and photo Notes: [bj] These were collected by Ralph Lingard many years ago. He gave them to me. I recalled he had a lot of them in a glass jar.
GOYAZITE on Quartz crystal Palermo Mine, Groton, NH 5 mm goyazite crystal on 2.5 cm quartz crystal	Species: GOYAZITE on Quartz crystal Locality: Palermo Mine, Groton, NH Specimen Size: 5 mm goyazite crystal on 2.5 cm quartz crystal Field Collected: Bob Janules Catalog No.: A Bob Janules specimen and photo Notes: This is a very large goyazite crystal !
FAIRFIELDITE Palermo Mine, Groton, NH 2.0 mm field of view	Species: FAIRFIELDITE Locality: Palermo Mine, Groton, NH Specimen Size: 2.0 mm field of view Field Collected: Clayton Ford Catalog No.: u2650 Notes: I am labeling this as fairfieldite. A single isolated crystal in a vug on lumpy jahnsite. With just a single crystal, I will never be certain, fairfieldite or messelite. Fletcher does have a lot of bermanite, a Mn phosphate. The decoration with small jahnsite and rockbridgeite balls adds interest.
JAHNSITE Group Palermo Mine, Groton, NH 3.2 mm field of view	Species: JAHNSITE Group Locality: Palermo Mine, Groton, NH Specimen Size: 3.2 mm field of view Field Collected: Clayton Ford Catalog No.: u2650 Notes: This lumpy ball form of jahnsite is common in Groton, NH pegmatites. Two high count, polished grain, EDS analyses indicated a chemistry of (4 P normalization): BC453A: Ca_0.73(Fe_1.96,Mn_0.36)_Σ2.57Mg_0.56Al_0.07P₄O₂₆ BC453: Ca_1.13(Fe_1.81,Mn_0.57)_Σ2.53Mg_0.38K_0.02P₄O_30.3 With Fe > Mn and Mg present, jahnsite group members jahnsite-(CaFeMg) or jahnsite-(CaMnMg) are suggested. I suspect intermediate compositions between these two defined species are allowed, which would best fit the BC453 chemistry.
