The entire lithology does fiz when 25 % HCl is dropped on sediment, so obvious indication that forams and other CaCO3 bearing fossils are present. | In smear slide inspection small amounts of forams were observed (~5 %), also ~2 % volcanic glass represented by clear shards of material. Remnants, small pieces of pumice were also observed. Shell fragments are seen. | 106.0-117.0 cm: Gradation from clay to pumiceous gravel matrix supported, in this case the matrix being the olive green clay from the above lithology.

Forams probably make up 10 % of the mud matrix, another 10-30 % is made up of volcanics. | 2010-09-27T12:41:13 |
