Resumo:

Light brown, coarse grained sediment with a few patches of a finer grained domain. Clasts range from small to medium in size. The finer grained domain mainly contains small sized grains that are very well dispersed. Clast shape ranges from angular to sub-rounded. Edge-to-edge grain crushing is common in the coarser domain, with a few grain stacks. The finer grained domain contains a few lineations.

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.

Resumo:

Dark brown sediment with organic matter. There are two main domains; a coarse grained domain, and a finer grained domain. The coarse grained domain contains grains ranging from small to medium in size, and angular to sub-rounded in shape. In the coarse grained domain, grain crushing/stacking is common, with a few lineations and rotation structures. In the finer grained domain, grains are small and range from sub-angular to sub-rounded in shape. Lineations are abundant in this domain.

Resumo:

Brown sediment with clasts ranging from small to medium in size. Clast shape ranges from sub-angular to rounded. Two mains domains can be observed; one mainly contains small clasts, and the other is a mix of small and medium sized clasts. The finer grained domain contains some organic material and is abundant in lineations. The coarser domain is also abundant in lineations but also contains crushed grains and comet structures.

Resumo:

Brown sample with two domains. One domain contains many small grains that are clustered together. The other domain is a darker brown and contains clasts that are well dispersed. The clasts range from small to large, and are angular to sub-rounded in shape. Lineations are commonly seen throughout both domains. A few rotation structures can also be seen in the well dispersed domain. Some grain crushing/ stacking can also be seen throughout the sample.
