Text Description: |
Yellow to gray in color and < 2cm thick. This unit is found only in the northwestern region of the island in one Campbell Lagoon section (Tannenbaum_1996_CL-03) and in one Onion Bay section (Tannenbaum_1996_OB-04). In section Tannenbaum_1996_OB-04 tephra KA might be mixed with tephra KB and in section Tannenbaum_1996_CL-03, tephra KA is located 4 cm below tephra KB. The stratigraphic position of the two units in section Tannenbaum_1996_CL-03 promotes the idea that post-depositional mixing of the two units may have occurred in section Tannenbaum_1996_OB-04. Stratigraphically the oldest unit, tephra KA is < 5 cm above latest-Pleistocene glacial till. At the Campbell lagoon exposure (Tannenbaum_1996_CL-03), tephra KA is 10 cm below unit KC, which has a maximum date of 8360 +/- 90 yr BP. Individual samples: 94KOD062, 94KODA098. |
