“FOV 1.4 x 1.8 mm. Via Jean-Pierre Beckerich et al. MOB coll.
These xls picked the tiniest cavity on the whole specimen to crowd into - not an easy shot! Better in stereo (child photo).
They are associated with gjerdingenite-Na and "eudialyte", neither of which is visible in the photo.
Updated with full res image June 2013.
