High-level Description: Unit 5. Sequence of 5 poorly-sorted, light grey or
brown laminae. Laminae consist of 10% olivine crystals, 10% red scoria, 40%
black scoria and 40% buff scoria. The sequence includes two coarse layers of
angular clasts (sub-mm to 1.5 cm) between three less coarse layers (sub-mm to
2 mm).

Texture
  Grain morphology and appearance: Small, angular to sub-rounded grains in a
clast-supported matrix, organized into laminar layers. Laminae consist of 10%
olivine crystals, 10% red scoria, 40% black scoria and 40% buff scoria.
  Grain size and sorting: Poorly-sorted clasts sub-mm to 2 mm diameter in less
coarse layers; sub-mm to 1.5 cm in coarser layers.
  Grain fabric:  Random orientation.

Sediment structure:  Parallel lamination.

Color:  Black and buff scoria, intermixed with red scoria and olivine
crystals.
