Text Description: Pods of reworked tephra occurring in the middle interglacial silt bed as well as in the immediately underlying loess (both UT1633 and UT1552). Type I beds have a low crystal content, abundant bubble-wall glass shards, pumice with large vesicles, and very small amounts of brown glass. Feldspar, orthopyroxene, and clinopyroxene are abundant with minor amounts of amphibole, magnetite, ilmenite, apatite, and zircon. From Preece et al. (2011): 5 cm thick; bubble-wall shards and pumice; in deformed peaty, organic rich silt; ~5.5 m above basal gravel and sand; field name 299h. Sample collected by J. A. Westgate, 1999.
