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:
Coarse grained sample with grains ranging from small to large in size. Clast shape ranges from sub-angular to well rounded. Edge-to-edge grain crushing is abundant throughout this sample. Minor amounts of rotation structures and lineations can also be seen.

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.
Resumo:
Brown sediment with two different domains; one coarse grained, and one finer grained. In the coarse grained domain, clasts range from small to large in size. The clast shape ranges from sub-angular to rounded. Rotation structures and edge-to-edge grain crushing is commonly seen. In the finer grained domain, clasts are mainly small, with a few larger clasts, and there is an abundance of lineations.
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:
Coarse grained sediment with clasts ranging from small to large. Clast shape ranges from angular to sub-rounded. Lineations are abundant in this sample, as well as grain crushing. Grain crushing is mainly edge-to-edge but there are also some grains that have been crushed into one another. Some rotation structures can also be seen.
Resumo:
Coarse grained sediment with grains ranging from small to large. Clast shape ranges from sub-angular to sub-rounded. Edge-to-edge grain crushing is abundant throughout the sample, along with lineations. Some grains are also crushed into one another. There are some areas of clay also within this sample.
Resumo:
Coarse grained sediment with clasts ranging from small to large. Clast shape ranges from angular to rounded. Lineations are abundant throughout the sample, along with rotation structures. Some comet structures and grain crushing can also be seen throughout the sample. Rotation structures can mainly be seen around larger clasts.
Resumo:
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:
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.
