Microscope snapshots of the four shocked zones. General overview (top, left) in cross-polarized light with labeled zones. Zone I (top, right) in cross-polarized light. Ol - m is an olivine grain in extinction position showing mosaicism, SV indicates an opaque shock vein. Zone II (middle, left) is in reflected light. Tr with an arrow indicates darker troilite melt veins intruding silicates. Zone III (middle, right) is in cross-polarized light. Remnants of silicate grains are surrounded by silicate melt, SV indicates an opaque shock vein. Zone IV is in cross-polarized (bottom, left) and reflected (bottom, right) light. New needle-sized olivine crystals with sharp extinction and eutectic metal and troilite grains (Eut) are visible.
