Sample type 1: Tephra Fall
Color: white
Final unit:
Text Description: Wispy, white, discontinuous tephra bed, occurs in the lower silt, 90 cm above tephra UT1052. Crystal-rich with abundant hornblende, plagioclase, and FeTi oxides and minor amounts of hypersthene and apatite. Its glass is mostly in the form of highly inflated pumice, although some chunky glass of low vesicularity is present. Mineral content consists of plagioclase, hornblende, and FeTi oxides with rare amounts of basaltic hornblende and apatite. From Preece et al. (2011): in silt of sedimentary fill incised into the Reid glacial drift; 90 cm above Sheep Creek-K (UT1052). Sample collected by B. Alloway, 1990.
