SaU 008 Olivine-Phyric Shergottite

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.
