Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.8 mm field of view
Field Collected: Walter Lane - ex. Gene Bearss
Catalog No.: u1244
Notes: This is the specimen in my New Hampshire mineral species display. My original photo taken in 2011 was a bit blurry, but the best I could do at the time. The specimen has several small sprays of falsterite. The specimen is firmly glued to the bottom of a 3/4 inch micro box, limiting the lighting and photo angles available. The randomly otiented, lustrous, blades make it impossible to avoid some reflections.
These February 2019 photos were taken with a Canon T3i camera, EFS 55 -250 mm lens with a Nikon Plan 10 objective on the end. Image stacks of 15 to 20 were processed with Helicon Focus, Method B. Walter Lane had these green-blue sprays identified as beraunite, a good guess at the time (1975). Falsterite was not defined until 2011.
