Stratigraphy
Formation:Barton Beds Member:Middle
Stratigraphic resolution:bed
Stratigraphy comments: Prestwich's stratigraphy is a bit screwy. No one else has recognized the London Clay in this area. This bed is probably part of the Barton Beds (Bosma, 1974). Gardner et al. are the first I've found who call these Barton Beds.
Lithology and environment
Primary lithology:shelly/skeletal,black,brown claystone
Secondary lithology:pebbly,green sandstone
Includes fossils?Y
Includes fossils?Y
Lithology description: a black shale with a very few shell s in seams and patches-in descending it becomes browner and very fossiliferous. At one location, is a layer of large septaria underlaid by a seam of small flint pebbles, immediately below which is thirty feel of greensand, in which fossils are extremely scarce-this then passes gradually into a brown clay with numerous shells and remains of Foraminifera, and then again into green sands with a few very small flint pebbles and traces of vegetable matter, but with few shells
Environment:marine indet.
