hello pete i think there is was hole inside the diogenite and than when it enter the atmosphere the resistance of air burn the fragile part of the diogenite and show the visicle that was inside , why , most of the 24370 gr taoudinid is formed from visicles, you can see photos they are very aparents, and an other collector told me this"" that it probably an ablation crater and not a true vesicle! """ but i would like to know what is the difrence between the two?? thanks aziz

Isn't a vesicle more of a trapped bubble within the material formed during the rock's formation?
