SaU 008 Olivine-Phyric
Paired with SaU 005, 051, 094,
060, 090, 120, 125, 130 and 150
SaU 008 has large olivine phenocrysts in a fine-grained groundmass of
pyroxene and maskelynite – feldspar that has been shocked into a glassy
form. Several shock melt pockets appear here as dark areas with
brown halos. Sample is 13.5 mm wide.
Shock pressures caused twinning and severe fracturing in this
pyroxene. Field of view is one millimeter wide.
In the center is a vesicle surrounded by quenched melt glass (with
other smaller vesicles) and partially melted and shock affected
pyroxene and olivine. Polarizing filters partially crossed.
Field of view is 1.7 mm wide.
