Text Description: Occurs in pods to 5 cm thick as a mixed, or layered, darked (5Y6/2) and lighter grey (2.5Y7/1) tephra that is interbedded with soliflucted, grey (2.5Y6/3) silt with oxidation nodules and layers of more and less compact silt. The boundaries between the colors are sharp and fairly well-layered to diffuse. In some pods, the colors are segregated to one part of the bed whereas other pods contain vertically repeated colors, mixed and subhoriztonal and giving a variegated appearance. One contact usually sharp whereas the other is less sharp. Repeated over 56 cm interval with solifluction folds. Some silt wisps intercalated with the tephra. References: ![]() ![]() ![]() ![]() |
