Figure F4. Photomicrograph of Sample 187-1152B-2R-1, 8-10 cm (see "Site 1152 Thin Sections"), showing an intersertal groundmass texture. Long acicular to prismatic to tabular crystals are plagioclase. Equant anhedral crystals clustered around plagioclase are clinopyroxene. Dark patches are areas of mesostasis.
