Figure F22. Photomicrographs of thin sections in cross-polarized light. Both figures show inclusions of glass, altered glass, and possibly clinopyroxene in plagioclase phenocrysts. Inclusions, with various morphologies, are mostly restricted to the phenocryst center. Rare inclusions are observed in clinopyroxene. Cpx = clinopyroxene, Pl = plagioclase. A. Sample 205-1253A-8R-1, 85-88 cm (thin section 15). B. Sample 205-1253A-8R-2, 52-55 cm (thin section 17).
