Hi Jerry and List,

Small crystals in chondrite vugs are not as unusual as one might think. The two most
famous chondrites in this respect are Baszkowka and Mount Tazerzait. They are very
porous and have numerous vugs that are coated with druse-like clear crystals, usually
stubby crystals of the main constituents of the meteorite: olivine, pyroxene, troilite,
and FeNi. These crystals (in Baszkowka and Mount Tazerzait) grew during equilibration
into the free space available.

Reference:

WLOTZKA F. et al. (1997) Petrography and noble gases of the unusual L5
chondrites Baszk?wka and Mt. Tazerzait (Meteoritics 32-4, 1997, A140).

Best wishes,

Bernd
