Figure F119. Photomicrographs of Sample 206-1256D-26R-2, 22-25 cm (plane polarized light). A. Brecciated glassy finger (dark brown) intruding crystalline basalt, both cemented by secondary minerals: amphibole, blue-green phyllosilicate, and later quartz (field of view = 10 mm). B. Detail of secondary minerals cementing breccia in A. Prismatic green amphibole, blue-green phyllosilicate, and glass replaced by saponite (brown) (field of view = 2.5 mm). C. Detail of B. Prismatic green amphibole, blue-green phyllosilicate, and glass replaced by saponite (dark brown) (field of view = 1.25 mm). D. Detail of secondary minerals cementing breccia in A. Acicular green to brownish green amphibole, saponite, and later quartz (field of view = 2.5 mm). E. Detail of B. Basal sections of green amphibole (field of view = 1.25 mm).
