Text Description: | Lowest tephra bed at station. Sample UT1409 is of the same tephra bed. This tephra marks the base of the third lithofacies unit at this station, and is 5.1 m above sea level. Ranges up to 5 cm thick and shows two discrete layers of light-tan, silt to medium sand grains separated by up to 1 cm of black silt in some areas. The lower layer is thicker and finer grained whereas the upper layer is coarser and pumice and phenocryst rich. Sample is dominated by low-vesicular pumice and has similar mineralogy and composition to samples UT1409 and UT1435. |
