Within the silt are 1- to 3-cm-thick, organic-rich bands and fine laminations of silt and tephra. The sample was collected 15 cm below tephra 96TOK1-13, from an isolated pod of clean, pumiceous, hornblende-rich tephra that appears salt-and-pepper in color. Highly vesicular pumice with an average grain size of 200 microns. |
