| Text Description: | Diffuse, discontinuous, gray tephra within inorganic loess 50 to 75 cm below Oct at two measured sections at Site B. Maximum thickness of 0.3 cm. Stratigraphic position relative to SC-F uncertain since they have not been found in the same section. SC-F tentatively placed stratigraphically below P11 because at all sites where it is found, P11 is within 1 m of OCt, while SC-F is generally 2 to 6 m below OCt. Distinct glass morphology, consisting almost entirely of blocky, thick-walled pumice, often elongate, with common microcryts and small, evenly distributed vesicles. Phenocrysts are rare and are dominantly plagioclase with minor amphibole. |
