PB #2B

Dark brown sediment that appears almost black. This may be due to organic content. Clasts are well dispersed and range from small to medium. The clast shape ranges from angular to sub-rounded. Lineations can be seen throughout the sample. Grain crushing can also be seen in minor amounts.

PB #7F TvDT

Dark brown, fine grained sediment. Mainly structure less with organic content. A few faint water escape structures can also be seen.

PB 3 (Y) KZ

Dark brown sediment, almost black due to organic material. Mainly structure-less with a few well dispersed clasts. Grains range from small to medium in size and sub-angular to rounded in shape.

PB 18 TVD

Dark brown sediment with organic material present throughout. The clasts are mainly small. Lineations are abundant throughout the sample.

PB 99 4B

Light brown sediment with clasts ranging from small to medium in size. The clast shape ranges from sub-angular to sub-rounded. Lineations are abundant throughout the sample. A few water escape structures can also be seen.

PB 1C(z)

Dark brown sediment with well dispersed clasts. The clasts are mainly small and range from sub-angular to rounded in shape. This sample is mainly structure-less but does contain lineations.

TvD PB #61

Brown sediment with well dispersed clasts ranging from small to large. Clast shape ranges from angular to sub-rounded. Lineations can be seen throughout the sample. There is one small patch of another domain present. This domain is light brown, and contains clasts that are clustered together. Grain crushing is abundant in this domain, as well as in other areas of the sample.

TVD #9 PB

Dark brown sediment (almost black), with a few clasts that are very well dispersed. The clasts range from small to medium in size. The clast shape ranges from sub-angular to rounded. The sample is mainly structureless. There are a few inclusions of a lighter domain. This domain contains more clasts than the darker one.
