DICKITE 2.5 cm specimen with 1.2 cm zone of pale blue dickite at top	Species: DICKITE Locality: Mine Ledge, Surry, NH Specimen Size: 2.5 cm specimen with 1.2 cm zone of pale blue dickite at top. Field Collected: Peter Cristofono - 2013 Catalog No.: 1889 Notes: Peter's 2013 find was the first reported occurrence of dickite in New Hampshire. This is the specimen that provided samples for the EDS and XRD analyses. The matrix is a fine-grained crystaline quartz.

DICKITE Mine Ledge, Surry, NH 4.5 cm specimen of pale-blue dickite in brown quartz	Species: DICKITE Locality: Mine Ledge, Surry, NH Specimen Size: 4.5 cm specimen of pale-blue dickite in brown quartz Field Collected: Tom Mortimer - 2014 Catalog No.: 1915 Notes:
DICKITE Mine Ledge locality, Surry, NH 5 mm field of view. DICKITE Mine Ledge locality, Surry, NH 0.2 mm white balls DICKITE Mine Ledge locality, Surry, NH 0.2 mm white balls DICKITE Mine Ledge locality, Surry, NH 10 cm specimen of goethite with white dickite balls at green arrow.	Species: DICKITE Locality: Mine Ledge locality, Surry, NH Specimen Size: Top photo, 5 mm field of view. Field Collected: Tom Mortimer Catalog No.: NC Notes: Pre EDS analysis, my best guess is dickite, an alternate habit of this species that has been confirmed from this locality. These tiny white balls are on a six inch, multi-pound, specimen of goethite-romanechite-hematite, 4th photo. Testing... not fluorescent (perhaps very weak, very pale green LW), and not a carbonate (flicked off a ball and pushed into a muriatic drop on a slide under my scope.... no bubbles) The balls are moderately soft. My initial thought was aragonite-calcite. Perhaps some sulfate, but I have not seen any sulfides at this locality. An EDS analyses confirmed dickite. The Al-Si ratio is the same as on a Kerry Day plot linked to my web site dickite top page.
