Scientific paper
The results of an analysis of the thermal history of green glass beads extracted from breccia 15427 in the north rim of Spur crater are reported. The vitrophyric beads were found to have lattice, fiber and polyhedral olivine morphologies. Cooling, heating, and crystallization experiments were performed with synthetically produced glass beads with the same compositions as the natural beads. The data indicated that the breccia samples cooled from 1000-1050 C at 1 C/sec, less than in free flight conditions. The homogeneity of the beads rules out solid rock impacts. The required cooling rate suggests that the process occurred in an atmosphere of volcanic gases. The suspension would have had to last at least 10 minutes.
