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.

Mainly a coarse brown sediment with a few patches of a finer grained domain. The clasts range from small to large in size and angular to sub-rounded in clast shape. The coarser domain mainly contains grain crushing and stacking, with some rotation structures. The finer domain mainly contains lineations.

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 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.

Resumo:

Brown sediment with multiple domains. There are two finer grained domains that contain a few small clasts. These two can be distinguished based on the abundance of clay material(darker brown). The coarse grained sediment contains clasts ranging from small to medium in size, and angular to sub-rounded in shape. This domain contains lineations, rotation structures, comet structures, and some edge-to-edge grain crushing.

Resumo:

Brown sediment with two main domains; a fine grained one rich in organic material and a coarse grained domain. The fine grained domain appears in several areas of the sample, and in one area alternates with the coarser domain. The coarse grained domain contains clasts ranging from small to medium in size, and angular to sub-rounded in shape. Grain crushing and lineations can commonly be seen in this domain.

Resumo:

Brown sediment with three main domains; two different fine grained domains and one coarse grained domain. The fine grained domains can be distinguished based on the abundance of organic material (darker). Both domains contain lineations. The coarse grained domain contains clasts ranging from small to medium in size and angular to rounded in shape. Rotation structures, lineations and comet structures can be seen in this domain. It also contains some fractured grains.
