Stratigraphy
Geological group: | Upper Ranikot | ||||
Local order: | bottom to top | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Shale unit (65 ft thick), at base of 365 ft thick section, underlying limestone, and overlying unfossiliferous sandstones and shales of the Lower Ranikot Series. This is the lowermost Upper Ranikot, and conformably overlies the Lower Ranikot Series, and is unconformably overlain by the Laki Series. The upper 300 ft of this section (including the collection) correspond to Vredenburg's Zone 1. Evidence for the lower Eocene age assignment is not presented, but the enterer suspects a microfaunal basis. Unit numbering is of the enterer's iniative and is numbered from bottom to top, each unit representing each of the author's lithological subdivisions. |
