Five samples of diamicts from different levels of the Miocene part of the CRP-1 core have been thin sectioned. Observations in the thin sections relate to texture, diagenesis, structure and plasmic fabric. The combination of observed microstructures leads to the interpretation that three samples are certainly indicative of grounded ice, e.g. they are basal tills, whilst the other two samples also possibly represent the same environment.
