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.
