Geography
Country: | Namibia | State/province: | Sperrgebiet |
Coordinates: | 27.4° South, 15.4° East (view map) | ||
Paleocoordinates: | 31.4° South, 8.6° East | ||
Basis of coordinate: | estimated from map | ||
Geographic resolution: | outcrop |
Time
Period: | Paleogene | Epoch: | Eocene |
Stage: | Priabonian | 10 m.y. bin: | Cenozoic 3 |
Key time interval: | Priabonian | Nannofossil zone: | NP 19-20 |
Age range of interval: | 37.71000 - 33.90000 m.y. ago |
Stratigraphy
Formation: | Langental Beds | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: The marine beds are only about 4 m thick. The age can be narrowly defined by the range overlap of Discoaster saipanensis and Isthmolithus recurvus. The former ranges from the middle to upper Eocene and the latter from upper Eocene to lower Oligocene. They co-occur only in the NP 19 and NP 20 zones of Martini's (1971) biostratigraphic zonal scheme, and only in the I. recurvus subzone of Bukry's (1975) zonal scheme. Informally named "Langental Beds." |
Lithology and environment
Primary lithology: | shelly/skeletal,green,yellow poorly lithified calcareous siltstone |
Secondary lithology: | concretionary,shelly/skeletal,gray,green,yellow lithified calcareous sandstone |
Includes fossils? | Y |
Includes fossils? | Y |
Lithology description: Concretionary calcareous sandstones and marly sandstones and siltstone. At least one layer of light-brown ferruginous calcirudite occurs near the bottom of the section. This layer contains pebbles, but is predominantly composed of neomorphosed mollusc fragments set in micrite and microspar. The marly sand- and siltstones are mostly pale greenish yellow, poorly consolidated, and calcareous. The calcareous concretionary layers are greyish yellow to pale greenish yellow and are moderately well indurated. | |
Environment: | shallow subtidal indet. |
Geology comments: Members of the nannofossil genus Braorudosphaera are virtually absent in open-ocean deposits, and are thus strong indicators of nearshore environments; Zygrhablithus bijugatus is also most common in nearshore waters. The benthic foraminifera also suggest a normal marine, shallow-water environment. |

Modes of preservation: | body |
Size of fossils: | macrofossils,mesofossils,microfossils |
