Resumo:

Coarse grained greyish brown sediment with clasts ranging from small to large. The majority of the sample contains small to medium sized clasts. Clast shape ranges from angular to sub-rounded. Edge-to-edge grain crushing and rotation structures are the most prevalent micro-structures in the sample. Many crushed grains can also be seen, along with lineations and occasional necking structures.
