Lithology and environment
Primary lithology:massive,white claystone
Includes fossils?Y
Lithology description: Bed 23 comprises a pale grey to almost white, massive clay, marl or impure limestone within which the degree of lithification is highly variable. This is the Fimbriata-waltoni Bed of previous studies (Horton et al., 1995). Small aragonitic bivalves (mostly Corbula) as well as naticid, cerithiid and planorbid gastropods are common in the more calcareous parts but are present as moulds elsewhere. Small dark fragments of both fusinite and lignite are common throughout.
Environment:lagoonal/restricted shallow subtidal
Geology comments: The facies of this unit suggests that it represents a larger scale, brackish water lagoon hemmed in by some form of barrier. Invertebrate and vertebrate biotas suggest a fluctuating salinity so it is likely that there were periodic influxes of seawater into the area which otherwise had a constant supply offreshwater from the land. Poorly developed calcrete nodules elsewhere in the succession and abundant evidence of biomass burning may suggest at least seasonal aridity.
