Lithology description, textural and structural observations, and indications for ground ice of sediment core CRP-2 (Table 1-4), supplement to: van der Meer, Jaap (2000): Microscopic observations on the frist 300 metres of CRP-2/2A, Victoria Land Basin, Antarctica. Terra Antartica, 7(3), 339-348

Jaap van der Meer
From the upper 300 m of CRP-2/2A, twenty-six samples of diamicts and deformation structures have been thin sectioned. These have been analysed for texture, structure, diagenesis and plasmic fabric. The combination of certain microstructures (e.g. turbate and linear) and plasmic fabric development is indicative of grounded ice. Clear evidence for two grounded ice events (three samples) was found in the upper Oligocene part of the core. The interpretation of ten more samples is less certain,...
