Resumo:
Coarse grained greyish-brown sample with clasts ranging from small to large in size. Clast shape ranges from angular to rounded. Edge-to-edge grain crushing and rotation structures are very common throughout the sample. Rotation structures can be seen around many of the large clasts. A few necking structures and lineations can also be seen throughout the sample. Although the grain crushing is mainly edge-to-edge, there are also many examples of grains that have been crushed into one another.
Resumo:
Coarse grained greyish brown sediment with clasts ranging from small to large. The majority of the sample contains small to medium sized clasts. Clast shape ranges from angular to sub-rounded. Edge-to-edge grain crushing and rotation structures are the most prevalent micro-structures in the sample. Many crushed grains can also be seen, along with lineations and occasional necking structures.
Resumo:
Coarse grained, dark brown sediment with clasts ranging from small to large in size. Clast shape ranges from sub-angular to sub-rounded. Rotation structures are abundant throughout this sample and can be seen surrounding clasts of all sizes. Comet structures, and lineations can also be seen. Minor amounts of grain crushing/stacking are also present in this sample
Resumo:
Coarse grained dark brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to rounded. Rotation structures can be commonly seen throughout the sample. They can be seen with and without central grains. Edge-to-edge grain crushing and crushed grains are also seen throughout the sample. This sample also contains minor amounts of lineations and comet structures as well.
Resumo:
Coarse grained, greyish brown sediment with clasts ranging from small to medium in size. The clast shape ranges from sub-angular to rounded. Lineations are abundant throughout the sample and can mostly be seen with smaller grains. Some rotation structures can also be seen in this sample. Minor amounts of grain crushing/stacking can be seen.

Coarse grained greyish brown sediment with clasts ranging from small to large. Clast shape ranges from angular to rounded. Rotation structures along with edge-to-edge grain crushing can be seen throughout this sample. Minor amounts of lineations and crushed grains can also be seen.
Resumo:
Greyish brown sediment with clasts ranging from small to medium. The clast shape ranges from angular to rounded. Lineations and comet structures are abundant throughout the sample. A few rotation structures can also be seen. Grain crushing and stacking are also visible in minor amounts.
Resumo:
Dark brown sediment with patches of darker organic rich material throughout. Clasts range from small to medium in size and sub-angular to rounded in shape. Lineations and grain stacking appear to be abundant throughout the sample. Minor amounts of edge-to-edge grain crushing and crushed grains are also apparent. Rotation structures and comet structures can also be seen in certain parts of the sample.

Resumo:
Greyish brown sediment with clasts ranging from small to medium in size. Clast shape ranges from sub-angular to rounded. Lineations and rotation structures are common throughout the sample. Rotation structures were seen around all sized clasts. This sample also contained a few areas of edge-to-edge grain crushing as well as crushed grains. Minor amounts of comet structures can also be seen.

Resumo:
Greyish brown sediment with clasts ranging from small to medium in size. Clast shape ranges from sub-angular to rounded. Lineations and rotation structures can be seen scattered throughout the sample. Comet structures can also be seen in certain areas of the sample. Minor amounts of grain crushing and stacking can also be seen.
Resumo:
Brown sediment with clasts ranging from small to large in size. Clast shape ranges from sub-angular to sub-rounded. Many larger clasts appear fractured and/or weathered. Lineations and rotation structures can be commonly seen. Comet structures are also present. Minor amounts of grain crushing and stacking can also be seen.
Resumo:
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.
