| Comment | Medium dark gray microvesicular intermediate to trachytic lava with common feldspar to 4 mm, most with conspicuous albite twins. Scarce to common (sensu mafic) mafics are mostly olivine to 3 mm, many entirely altered to orange hematitic masses, but some with relict cores and rims, and lesser black pyroxene. Larger vugs to 3 mm near weathered surfaces are filled with very coarse white secondary mineral, probably calcite. |
