All specimens in this update set came from a single tennis ball-sized rock found in a tub of phosphate samples gifted by Bob Whitmore.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 4 mm field of view.
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2380
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 6 mm siderite crystal with clear quartz crystal in center
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2381
Notes: From a 160 image stack.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.7 mm field of view. Black siderite scalehedron.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2390
Notes: Best guess on the white acicular mineral is strunzite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.45 mm field of view.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2390
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1.5 mm field of view.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2387
Notes:Very dark-blue mass of dendritic crystals. Appears to be post-mining growth. There is much chalcopyrite on this specimen including directly beneath this mass, so some secondary copper mineral is suspected. Janet Cares reported djurleite, Cu31S16 ,from Palermo.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.7 mm mass of blue-black bornite
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2403
Notes: From a 50 image stack.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.4 mm field of view.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2386
Notes: Best guess on this white acicular mineral is childrenite. Presently labeled as hydroxylapatite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 5 mm field of view. Green pseudomalachite crust on milky quartz
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2393
Notes: A blob of chalcopyrite is in the lower left; the likely source of copper for the pseudomalachite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2 mm field of view. Chalcopyrite with bornite film coating.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2393
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2.6 mm childrenite crystal
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2388
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1.8 mm tall columnar cluster of milky apatite crystals.
Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore
Catalog No.: u2391
Notes: My [tm] EDS experience has been that most Palermo white to milky apatite crystals are hydroxylapatite. However visually distinguishing different apatite species is risky.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.7 mm cluster brown, furry, balls on cream-colored siderite
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2400
Notes: One possible ID is goethite.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.6 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2399
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 1.1 mm field of view and 0.6 mm zom view.
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2395
Notes: This Palermo cacoxenite compares very favorably with many cacoxenite photos on mindat.org.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 2.6 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2407
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.5 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2407
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.7 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2402
Notes: The pre-breakdown specimen that hosted these cacoxenites had a moderate amount of chalcopyrite. Some of the chalcopyrite was altered to this blue-black mineral here, (perhaps bornite). Cacoxenite is rare at Palermo. I wonder if the chalcopyrite enables the favorability of cacoxenite formation.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 1.1 mm glassy green crystal
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2383
Notes: Kulanite - Bjarebyite form a Mn-Fe series. A chemical analysis is required for differentiation per Whitmore & Lawrence's book The Pegmatite Mines Known as Palermo.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 0.8 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u2397
Notes: From the rock chunk with cacoxenite.
