| Text Description: | The only sample of Jensen_Palisades-6 (what it is labelled as in Table 1 of Jensen and others, 2013) and also the only sample collected in the river level peat (Site F) that formed a distinct, traceable unit (see Fig. 4 in Jensen and others, 2013). Creamy yellow in color, up to 1 cm thick, and laterally continuous within organic-rich silt that contains abundant plant macrofossils and peat lenses, grading down to compact peat at river level. Approximately 2 m above river level, and ~1 m above the numerous reworked blebs of tephra that collectively comprise the lowermost tephra beds at the Palisades (i.e. Jensen_Palisades-1 through 5). Glass morphology is almost exclusively thin tricuspate and bubble-walled shards; mineralogy dominated by plagioclase and pyroxene. |
