Resumo:

Coarse grained sample with multiple fine grained domains. Clasts range from small to medium and sub-angular to sub-rounded. Mainly contains grain crushing (with grains crushed into one another) and short distance lineations. A few rotation structures are seen and fine grained sand domains can also be seen.

Resumo:

Brown sediment with a coarse grained domain and a fine grained domain. The coarse grained domain contains clasts that are small to medium in size. The clast shape ranges from sub-angular to sub-rounded. The coarse grained domain is abundant in lineations. The fine grained domain contains many faint water escape structures. A few rotation structures can also be seen throughout the sample.

Resumo:

Brown sediment with a coarse grained domain and a few finer grained domains throughout the sample. Clasts range from small to large in size and angular to sub-rounded in shape. In the coarser domain, grain crushing is common. A few rotation structures can also be seen throughout the sample, along with lineations.
