Finer fraction from ‘Core 8’optical image – mount is ~10 mmdiameter; note shell fragments
Samples were washed briefly in distilled water, rinsed in methanol, air-driedmounted on aluminum stubsusing double-stick tape
Coarser fraction from ‘Core 8’Optical image – mount is ~10 mmNote seed casing (arrow); fragment of gypsum crust
Finer fraction from ‘Core 12’Optical image – mount is ~10 mmquartz, k-feldspar are dominant mineralsdarker grains are rock fragments
Coarser fraction from ‘Core 12’note rounding of larger grains of quartz
