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:

This sample contains multiple domains. One domain is a fine grained greyish-brown ground mass, with some small clasts. Another domain is a dark grey, structure-less ground mass. Another domain is a light greyish-brown domain that is generally fine grained with clay inclusions.
