Resumo:
Fine grained, dark brown sediment. Minor amounts of lineations can be seen. Faint water escape structures are also abundant.
Resumo:
Dark greyish-brown sediment with clasts ranging from small to large in size. Clasts are sub-angular to sub-rounded in shape. Fine grained domains can be seen scattered throughout the sample. The sample also contains comet structures, lineations, and minor amounts of rotation structures within the coarser domain.
Resumo:
Multiple domains are present. Clasts range from small to large in size and sub-angular to sub-rounded in shape. The fine grained domain is dark brown with some lineations and organic material. The coarse grained domain is grey in colour and contains mainly lineations and rotation structures. Some comet structures can also be seen.
Resumo:
Mainly coarse grained with a separate fine grained clay domain occurring throughout the sample. The coarse grained domain contains clasts that range from small to medium in size. The clast shape ranges from angular to sub-angular. Grain crushing is abundant in this sample, along with lineations, and minor amounts of rotation.
Resumo:
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.
Resumo:
Brown, fine grained sediment. Clasts are small. Some organic material can be seen (darker). Lineations are common throughout the sample.
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 clasts ranging from small to medium in size. Clast shape ranges from angular to rounded. Lineations and grain crushing are abundant throughout the sample. This sample also includes several inclusions of darker and fine grained domains. Comet structures can also be seen in some areas of the sample.
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:
Light brown sediment with clasts ranging from small to medium in size. The clast shape ranges from sub-angular to sub-rounded. Rotation structures can commonly be seen, along with some comet structures as well. A few lineations and edge-to-edge grain crushing can also be observed. There is also the inclusion of a fine grained domain that is a darker brown (tanned-brown).
Resumo:
Dark brown, fine grained sediment. Mainly structure less with organic content. A few faint water escape structures can also be seen.
Resumo:
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.
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:
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.
Resumo:
Dark grey ground mass with clasts ranging from small to large. The clast shape ranges from sub-angular to sub-rounded. Lineations can be seen throughout the sample. Clasts are generally well dispersed.
