Resumo:

Brown sediment with multiple domains. There are two finer grained domains that contain a few small clasts. These two can be distinguished based on the abundance of clay material(darker brown). The coarse grained sediment contains clasts ranging from small to medium in size, and angular to sub-rounded in shape. This domain contains lineations, rotation structures, comet structures, and some edge-to-edge grain crushing.

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.
