Resumo:
Coarse grained sample with clasts that range from small to large in size. The clast shape ranges from angular to rounded, and many grains are fractured. Grain crushing is present in large amounts. This includes edge-to-edge crushing as well as grains that are crushed into one another. Rotation structures are also common among the clasts that are sub-rounded to rounded. Areas of finer sediment can also be seen.
Resumo:
Mainly a coarse brown sediment with a few patches of a finer grained domain. The clasts range from small to large in size and angular to sub-rounded in clast shape. The coarser domain mainly contains grain crushing and stacking, with some rotation structures. The finer domain mainly contains lineations.
Resumo:
Brown sediment with clasts ranging from small to large in size. The grain shape ranges from angular to rounded. Grain crushing is abundant throughout the sample, along with rotation structures surrounding larger clasts. Lineations and and areas of clay can also be seen. A few necking structures are also present.
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 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:
Coarse grained sample with multiple fine grained domains. Clasts range from small to medium and sub-angular to sub-rounded. Mainly contains grain crushing (with grains crushed into one another) and short distance lineations. A few rotation structures are seen and fine grained sand domains can also be seen.
Resumo:
Coarse grained sediment with a few fine grained matrices. Brown sediment with small to medium sized clasts. Clasts range from sub-angular to sub-rounded. Organic material present. It contains rotation structures throughout as well as edge-to-edge grain crushing. Fine grained clay domains are present and lineations can also be seen. Minor amounts of grain stacking can also be seen.
Resumo:
Brown, coarse grained sample. Clasts range from small to medium in size and sub-angular to angular. Patched of clay rich domains can be seen throughout the sample. Rotation with and without a central grain can be seen throughout the sample. Edge-to-edge grain crushing and grain stacking can be seen throughout the sample.
Resumo:
Dark brown sediment with sub-angular to sub-rounded grains, that range from small to medium in size. Lineations with fractured grains are abundant, and grain crushing can also be seen. Minor rotation can also be seen.
Resumo:
Coarse grained sediment with fine grained domains, clay material, rotation structures and lineations. Clasts range from sub-angular to sub-rounded. Mainly brown sediment with darker patches of brown throughout. Major amounts of grain crushing can be seen in the coarse grained material.
Resumo:
Coarse grained sample with sub-angular to sub-rounded clasts ranging from small-large in size. Rotation structures, grain crushing and lineations were seen throughout the sample.
Resumo:
Coarse grained sample, with generally medium sized clasts. Clasts were sub-angular to sub-rounded. Many rotation structures, as well as large amounts edge-to-edge grain crushing are also present.
Resumo:
This is a coarse grained sample with some very fine grained domains throughout the sample. The clast shape and size range from small to large, as well as angular to sub-rounded. Grain crushing is the most prevalent in this sample. It also contains some rotation structures and minor necking structures. Lineations and grain stacking can also be seen.
