High-level Description: Unit 10. Scoria layer 6 cm thick. Poorly-sorted
sequence of 5-6 discontinuous laminae, comprised of repeating coarse and fine
layers of fine and coarse ash. Larger clasts (up to 2 cm) interspersed
throughout. Coarse layers are grey, fine are buff. A few olivine grains are
also evident. Layer is similar to Unit 6, though very thin fine ash layers are
1-2 mm thick. Coarse layers dominate.

Texture
  Grain morphology and appearance: Small, angular to sub-rounded grains in a
clast-supported matrix, organized into laminar layers. Coarse layers are more
homogeneous in grain size (1-3 mm) than finer layers, which contain a few
larger (0.5-1 mm diameter) grains. Texture is rough and rubbly. Some olivine
grains are present.
  Grain size and sorting: Poorly-sorted clasts, fine- to coarse-ash (0.5-3
mm).
  Grain fabric:  Random orientation.

Sediment structure: Parallel lamination.

Color:  Grey, black, with some green-clear olivine.
