Figure 7 (A). Photomicrograph of shock melted fragments of spherulitic glass from Bedout 3044 m (9986 ft) set in a matrix of dark glass. Similar spherulitic glass has been identified in other terrestrial craters (Chicxulub, Sudbury). Width of slide is 1.0 mm. Figure 7 (B). Back Scattered Electron Image of another spherulitic glass fragment from Bedout at 3044 m (9986 ft). The large grain of nearly pure silica (Table S-1, analyses #22 and #24). Similar textures have been observed in BSE images of the Chicxulub suevite. Scale bar is 50 µm.
Figure 7 (C). Back Scattered Electron Image of high silica glass from Bedout 3044 m (9986 ft.) The large grain of nearly pure silica (analyses #22 and #24) in the center of the image is set in a matrix of plagioclase, altered glass and Fe-Ti oxides. Note the dark and light areas of the BSE image that correspond to different levels of impurities in the silica glass. Oridinary volcanic processes cannot produce glass of >85% silica. Scale bar is 50 µm.
