Type Locality:

The formations of the Wilkie Point Group are defined in the Elf Jameson Bay C-31 well (76°40'12''N, 116°43'45'') (Embry, 1984b).

Distribution:

Occurs in the central and eastern Sverdrup basin. Souther (1963) studied and named the Savik Formation of central Axel Heiberg Island. Tozer (1963a) extended the Savik Formation over much of Axel Heiberge and western Ellesmere. Stott (1969) mapped Ellef Ringnes Island and on Reindeer Peninsula he recognized the Savik Formation. On Amund Ringnes, Balkwill (1983) mapped the Savik Formation. He also recognized an "Upper Savik" unit on Cornwall Island. On King Christian Island, Balkwill and Roy (1977) subdivided the Savik Formation (Embry, 1984b).

Lithology:

In ascending order the four formations of the Savik Group and their dominant lithologies are: Jameson Bay (shale-siltstone), Sandy Point (sandstone), McConnell Island (shale-siltstone), and Hiccles Cove (sandstone) (Embry, 1984b).

Relationship:

Strata previously assigned to the Savik Formation are now placed in the Jameson Bay, Sandy Point (thin or absent), McConnell Island and Ringnes formations. The term Savik is retained and is given group status because it is a useful mapping unit on Axel Heiberg Island where it forms a recessive interval between the resistant Heiberg and Awingak formations. The name Wilkie Point now refers to a group and is used in basin margin areas where sandstones of the Sandy Point and Hiccles Cove formations are prominent. "Jaeger" was used for a variety of stratigraphic units and consequently the term was abandoned. In the central and eastern Sverdrup the Jameson Bay conformably overlies the Heiberg Formation. Over most of the Sverdrup the Jameson Bay is conformably overlain by the Sandy Point Formation. In the basin centre the Sandy Point is absent due to facies change and the Jameson Bay is conformably overlain by the McConnell Island Formation. The McConnell Island Formation overlies either the Sandy Point Formation or Jameson Bay Formation. Along the margins of the basin the McConnell Island is conformably overlain by the Hiccles Cove. Basinward, the Hiccles Cove passes laterally into McConnell Island shale that is conformably overlain by the Ringnes Formation. The Hiccles Cove is overlain by the Ringnes Formation. The contact is conformable in most areas but is unconformable at the basin margin (Embry, 1984b).

History:

Embry (1984b) raised the Savik Formation to group status and proposed four new formations: the Jameson Bay, Sandy Point, McConnell Island and Hiccles Cove formations.
