Resumo:
Dark brown sediment with clasts ranging from small to large in size. Grain shape ranges from angular to rounded. Lineations can commonly be seen throughout the sample. Many clasts are fractured and/or weathered. Necking structures, some rotation structures, and minor amounts of grain crushing can also be seen.
Resumo:
Greyish-brown sediment with clasts ranging from small to large in size. Grain shape ranges from angular to rounded in shape. Many grains appear to be fractured or weathered. Lineations and rotation structures are abundant within this sample. Grain crushing and stacking can also be seen in this sample. Comet structures are also present in minor amounts.
Resumo:
Greyish brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to rounded. Many grains in this sample are fractured. Rotation structures and lineations are the most common micro-structures that can be seen in this sample. Grain crushining, grain stacking, and comet structures can also be seen.
Resumo:
Dark grey sediment with clasts ranging from small to large size. Grain shape ranges from angular to rounded. Many grains are fractured and weathered. Necking structures, along with rotation structures, are very common in this sample. They can be seen between many of the larger aggregates. Lineations and grain crushing are also present throughout.
Resumo:
Dark grey sediment with clasts ranging from small to large in size. Grain shape ranges from angular to rounded. Many grains are fractured and/or weathered. Edge-to-edge grain crushing is abundant in this sample, and some crushed grains can also be seen. It also contains lineations and rotation structures throughout. Minor amounts of comet structures can also be seen.
Resumo:
Dark grey sediment sample with clasts ranging from small to large in size. Clast shape ranges from angular to rounded. Lineations and grain crushing are the most abundant. Necking structures and rotation structures can also be seen throughout the sample mainly between/surrounding larger aggregates. A few comet structures can also be seen.
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.
Resumo:

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.
