Brown sediment clasts ranging from small to large in size. Clast shape ranges from angular to sub-rounded. Water escape pathways can be seen in this sample. It also contains a fine grained sand domain. Lineations are also commonly seen in this sample. Minor amounts of grain crushing and rotation structures can also be seen.

Brown sediment with two main domains; a coarse grained domain and a fine grained domain. Clast size in the fine grained domain is mainly small. The coarser domain contains clasts ranging from small to large in size. The clast shape ranges from angular to rounded. Necking structures are commonly seen in the coarser domain. This domain also contains many rotation structures and lineations. The fine grained domain exhibits multiple water escape pathways, along with lineations. There are also minor amounts of grain crushing present within this sample.

Resumo:

Dark brown sediment with two domains. One domain is fine grained, while the other is coarser grained. Clasts range from small to large, and sub-angular to sub-rounded in shape. The coarser domain contains lineations, comet structures and minor amounts of rotation structures. The fine grained domain is abundant with water escape structures. This sample also contains a few different areas of clay rich sediment.

This sample contains a fine grained, dark grey ground mass with well dispersed clasts. Clasts are not abundant but range from small to large. The clast shape ranges from sub-angular to sub-rounded. A few faint rotation structures can be seen. Minor amounts of lineations can also be seen.

Dark brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to sub-rounded. Lineations can be seen throughout the sample, along with a few rotation and comet structures. This sample also contains a fine grained clay domain that is relatively structure-less. It can be seen scattered throughout the sample.

Resumo:

Brown sediment with clasts ranging from small to large. Clast shape ranges from angular to sub-rounded. Lineations are common throughout the sample. This sample also contains a clay domain, that appears very fine grained. Edge-to-edge grain crushing, comet structures, and rotation structures are also present.
