Found 1996. This is a close-up view of the leached cryolite found in the contact zone exposed in the SE part of the quarry in December 1996. According to the Min Rec special article on this quarry (1998, p. 109), the cavitiy walls are encrusted with numerous small (0.2 – 0.5 mm), tabular crystals of thomsenolite, and the small powdery white areas are probably a mixture of gibbsite and doyleite. When looking at this specimen through a scope, one can see that there are tiny crystals lining the cavities, but I was not able to find any larger than 0.1 mm. That’s too small for me to photograph clearly, but you can see my attempts at \u003Ca rel=\"nofollow\" class=\"external autonumber\" href=\"https:\u002F\u002Fwww.mindat.org\u002Fphoto-1181518.html\">[1]\u003C\u002Fa>.
