Whiting Sandstone Unit

Computer Code: WHISA Preferred Map Code: notEntered
Status Code: Full
Age range: Turonian Age (KT) — Coniacian Age (KO)
Lithological Description: The Whiting Sandstone Unit consists of white to grey or grey to brown or occasionally green, very fine- to medium-grained, well-sorted, poorly cemented, partly laminated, micromicaceous sandstones with interbedded mudstones, silty mudstones and minor amounts of limestones. The mudstones and silty mudstones are grey to dark grey, green or red to brown, moderately firm, partly calcareous and carbonaceous.
Definition of Lower Boundary: In the West Shetland Basin, the Whiting Sandstone Unit (e.g. 206/10a-l) and the Dab Limestone Unit (e.g. 206/8-4) rest unconformably on the Clair Group and Victory Formation, respectively.
Definition of Upper Boundary: On wireline logs, the top of the unit is represented by a sudden downward decrease in gamma-ray log values and an increase in velocity as Kyrre Formation mudstones grade to Whiting Sandstone Unit sandstones, siltstones and limestones.
Thickness: none recorded or not applicable
Geographical Limits: Restricted to the northern part of the West Shetland Basin.
Parent Unit: Kyrre Formation (KYRE)
