Text Description: 30-cm-thick-tephra; consists of thin, bubble-wall shards. Orthopyroxene, plagioclase, magnetite, and ilmenite are relatively abundant in the small crystal component, which also contains minor amounts of clinopyroxene, apatite, and zircon. Sharply defined basal contact with underlying loess. From Preece et al. (2011): <30 cm thick; bubble-wall shards, trace amounts of brown glass; in silt; field name RB-T
