Specimen Size: 0.5 mm bipyramidal crystal
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo
Notes: [bw] "This isn't the best or the sharpest torbernite xl I have. In fact, it's a little granular. At the beginning stage of deterioration? But ... it's ... probably the best example of a bipyramidal one that I have from anywhere. My Plume ones are a little on the big s side and look paler than when I put them in boxes." [tm] Torbernite crystals seem to loose their intense green color as they age.

Locality: Parker Mtn. Mine, Strafford, NH
Specimen Size: 1.0 field of view. Lusterus cookeite clusters on tip of quartz crystal
Field Collected: Neil Santerre
Catalog No.: u1450
Notes: My expectation for capturing much definition of these lusterus micaeous cookeite balls was low. Even with diffused fluorescent lighting my expectation proved correct. (A stack of 105 images.)
The first report of cookeite at the Parker Mtn. Mine that I found was Geology of New Hampshire - Part III Minerals and Mines by Meyers and Stewart, Table 1, pg 84. No supporting reference is cited. Rocks & Minerals 1989, Vol. 64, #6 includes cookeite in a report on Parker Mtn. Mine. In this note, Dana Morong reported the minerals found at Parker by Phillip Foster. It is unknown how the how/if the identification was confirmed.
Mindat.org lists two polytypes of cookeite: Cookeite-1A, triclinic and cookeite-2M, monoclinic. Unknown which "flavor" this Parker Mtn. occurrence is.
