Figure F29. The variety of lithic and vitric clast types in Sample 192-1184A-31R-7, 40-43 cm, Subunit IID. In decreasing order of abundance, the clast types are nonvesicular basalt, vitric shards, sparsely vesicular basalt, plagioclase-rich basalt, and tachylite. Glass is completely altered to smectite, and the cement is composed mainly of zeolites (field of view = 5.5 mm; plane-polarized light; photomicrograph ID# 1184A
