SOME FRACTION OF THE WILD 2 PARTICLES THAT IMPACTED THE UNDER-DENSE DENSITY-GRADED SILICA AEROGEL AT 6.1 KM/S INTERACTED WITH SILICA MELTS AND PERHAPS EVEN SIO VAPOR. FOR THE PURPOSE OF THIS WORK I DEFINED TWO THERMAL DISCONTINUITIES ALONG A STARDUST TRACK VIZ.: (1) AT AND NEAR TO THE PENETRATION HOLE AND (2) AT THE BULB TO STYLUS TRANSITION IN TYPE B AND C TRACKS AND RARE AT THE MAIN-TRACK TO STYLUS TRANSITION IN TYPE A TRACKS. THE PROPOSED HIGH-RESOLUTION TRANSMISSION ELECTRON MICROSCOPE STUDY WILL FOCUS ON THE DETAILED CHARACTERIZATION OF THE RESULTS OF THESE INTERACTIONS AT AND NEAR TO THE LOCATIONS ALONG STARDUST TRACKS. THESE INTERACTIONS ARE EXPECTED TO HAVE A CHAOTIC NATURE AT THE FIRST DISCONTINUITY AND MAY BE A MIXTURE OF EQUILIBRIUM AND NON-EQUILIBRIUM REACTIONS BUT WILL BE MORE MUCH LESS SO AT THE SECOND ONE. CONTRIBUTING FACTORS TO THE NATURE OF THESE INTERACTIONS INCLUDE WILD 2 GRAIN SIZE AND FRAGMENTATION AND FORMATION OF NANOGRAINS AT TEMPERATURES WELL BELOW THE MELTING POINT OF THE BULK MATERIALS (I.E. WILD 2 MINERALS).
