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 multiple domains. Grains range from small to large in size, and angular to sub-rounded in shape. Large amounts of grain crushing can be seen in the coarser domains. The sample is mainly dominated with grain crushing. The finer grained domains contain some clay rich material. Some lineations and rotation structures can also be seen throughout the different domains.
