Figure F114. A. Close-up photograph of hyaloclastite breccia containing a large clast of fresh brownish glass at 51-57 cm, which is highly fractured and brecciated at the margins and surrounded by smaller clasts. The rims of clasts of brownish fresh glass are altered to and cemented by a dark phyllosilicate (possibly saponite) (interval 206-1256D-51R-2, 47-59 cm). B. Close-up photograph of hyaloclastite breccia containing clasts of fresh brownish glass and of microcrystalline basalt (light gray at 0-5 cm, and 11-13 cm). The rims of clasts of brownish fresh glass are altered to and cemented by a dark phyllosilicate (possibly saponite) (interval 206-1256D-30R-1, 0-14 cm).
