Stratigraphy
Geological group: | Purbeck | Formation: | Lulworth | Member: | Worbarrow Tout |
Local section: | Durlston | Local bed: | DB 102/103 | ||
Local order: | bottom to top | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Uppermost Lulworth Beds of Casey 1963, lying just below the Cinder Member, the base of which currently marks the Jr/K boundary in Southern England. Section originally published by Ensom 1985. Correlated with horizon DB102 in Durlston Bay.
Ensom & Sigogneau-Russell (1998, p. 35): The upper horizon lies at the junction of a clay, locally termed the 'Sly', which immediately underlies the 'Cap' bed, 2.6 m below the base of the Cinder Member. This clay-limestone interface can be equated confidently with beds DB 102/103 in Durlston Bay (CLements 1993). Cherty Freshwater Mbr now = top of Worbarrow Tout Mbr. |
Lithology and environment
Primary lithology: | cherty/siliceous "limestone" |
Secondary lithology: | argillaceous,calcareous claystone |
Includes fossils? | Y |
Lithology description: A sequence of thin limestones, micrites, argillaceous micrites, calcareous shales and clays. The limestones often contain nodules of chert. | |
Environment: | lacustrine - small |
Geology comments: Conditions of deposition generally brackish or freshwater, though there are occasional appearances of almost normal marine fauna. Clays may represent mud flats bordering a freshwater lake.
Ensom & Sigogneau-Russell (1998, p. 35): The sedimentology and environmental setting of the upper horizon has been described by West (1988). Both horizons are thought to represent clays bordering shallow freshwater lakes |
