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.
