6. Freshly broken surface of ankaramite from Rarotonga, Cook Islands pyroxene olivine amygdule (former vesicle, now filled with some sort of secondary mineral)

7. Vesicular basalt (from Kohala) with lots of little clusters of plagioclase feldspar phenocrysts (and a few olivine phenocrysts). plagioclase feldspar olivine vesicle (frozen bubble)
