Resumo:
Dark brown sediment with mainly small grains. Clasts are sub-angular. Abundant in lineations, grain stacking, and minor grain crushing. Lineations are oriented in multiple directions.
Resumo:
Brown, coarse grained sediment , with clay material. Clasts range from small to large, and sub-angular to sub-rounded. Organic material can be seen. Lineations are abundant. Grain stacking edge-to-edge grain crushing can also be seen. Organic material can be seen. Edge-to-edge grain crushing is seen throughout the image. Contains the inclusion of a finer domain.
Resumo:
Coarse grained brown sediment with angular-sub-angular grains. Contains mainly medium sized clasts with a few smaller aggregates. A dark organic rich domain can be seen within this sample. Grain crushing (edge-to-edge and into one another) can be seen alongside with grain stacks, and silt caps.
Resumo:
Coarse grained sample with sub-angular to sub-rounded clasts. Clasts range from small to medium sized. Major grain crushing seen throughout the sample. Grain stacking and lineations are also present. A dark organic rich domain can be seen within the sample.
Resumo:
Brown to dark brown sediment with small to medium sized clasts ranging from sub-angular to sub-rounded. This sample contains a coarse grained domain and a fine grained domain. Clear boundaries can be seen. Grain stacking can be seen in the coarse domain, while lineations are the dominant microstructure in the fine grained domain. Minor grain crushing can also be seen. Some of the coarser domain is rich in clay and organics.
Resumo:
Dark brown sediment with clasts that range from small to large. The clast shape ranges from sub-angular to sub-rounded. Lineations are abundant in this sample. Edge-to-edge grain crushing can also be seen. Darker organic rich domains are also present throughout the sample.
Resumo:
Coarse grained sediment with clasts ranging from small to medium in size. Clast shape range from sub-angular to sub-rounded. Lineations are present throughout the sample. Edge-to-edge grain crushing, grain stacking, and comet structures can also be seen. Some grains are crushed into one another. Areas of finer sediment can also be seen.
Resumo:
Two main domains can be seen in this sample. One is coarse grained with clasts ranging from small to medium in size. The other is very fine grained, and a very dark brown, potentially influenced by organic material. Grain crushing and lineations can be seen in the coarser domain.
Resumo:
Coarse grained sample with inclusions of finer grained sediment. Clasts are small to large in size and angular to sub-rounded in shape. Grain crushing is abundant in this sample, and lineations and minor grain stacks can also be seen.
Resumo:
Dark brown sediment with mainly small clasts. The clasts range from sub-angular to sub-rounded. Lineations are abundant throughout the sample. Comet structures are also present throughout the sample. Minor amounts of grain crushing and stacking can also be seen.
Resumo:
Grey sample with clasts that range from small to medium in size. The clast shape ranges from angular to sub-rounded. It mainly contains lineations and grain crushing. A few comet structures are also visible throughout the sample.
Resumo:
Dark brown sample with clasts that range from small to large. The clast shape ranges from angular to sub-rounded. Grain crushing is present in this sample along with some lineations. Faint water escape structures can also be seen.
Resumo:
Light brown sediment with mainly small clasts. The clasts are sub-rounded in shape. Lineations are abundant. Grain crushing and stacking are also present.
Resumo:
Brown sediment with clasts ranging from small to medium in size. The clast shape ranges from angular to sub-rounded. Lineations are abundant in this sample. Faint water escape structures can also be seen as well as grain crushing/stacking.
Resumo:
Brown sediment with organic matter and clasts ranging from small to large. The clast shape ranges from sub-angular to sub-rounded. Lineations and grain stacking are the most abundant in this sample. Minor amounts of grain crushing can also be seen.
