Jason, your observation is spot on and well taken While I did mention CRE ( Cosmic Ray Exposure) analysis, my thoughts were more of being able to analyze the mechanics of the fragmentation by observing/matching features from the different adjacent surfaces.. e.g. were chondrules split in two or did the matrix separate around chondrule surfaces. If so, what was the secondary ablation loss between surfaces? Was there evidence of micro spalling on adjacent surfaces evidencing the difference in internal vs surface temperatures. So many fragments seems would give rise to analyzing some very esoteric musings that might give insight into factors which control fragmentation.
Back to pairs, I imagine some directly matching fragments in other stones might be used if one took a laser topography series so the surface could be digitally analyzed looking for specific chondrule sites on both sides to see if the sheer amounted to fracturing undulating within the matrix or the sheer was so specific the rupture also split chondrules. Perhaps a good thesis project for some grad student somewhere, sometime.
