Text Description:
Lithic sample, presumably of pre-existing dome. Initial sample was 15x12x15 cm weighing approximately 2 kg. Sample is a flat-sided, irregular hexagon column fragment, and is uniformly 40% gray; groundmass is dominantly coarsely crystalline plagioclase and pyroxene, approximately 5% void space (voids <1 mm); medium gray interstitial groundmass is finely crystalline, +/- glass.
