Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name Cutbill & Challinor (1965) introduced the term “Billefjorden Group” for a suite of nonmarine sediments now recognised to be of late Devonian to early Carboniferous age. The type area is in the environs of Billefjorden in central Spitsbergen. The Billefjorden Group is a well-established lithostratigraphic unit and its overall facies development and depositional evolution is well known (e.g. Gjelberg 1981; Steel & Worsley 1984). Lower Carboniferous units in the southern Norwegian Barents Sea are herein also assigned to the group. The offshore development of the group resembles that described from onshore with one major exception: the upper part of the group includes some shallow marine deposits in the southeastern Finnmark Platform. As yet enigmatic red-bed sequences on the Loppa High are also tentatively assigned to the group, but need further investigation (see below).
Offshore reference areas The Barents Sea subsurface reference area is located on the eastern Finnmark Platform (Fig 9.1 , 9.2 , 9.7) , where the Billefjorden Group has been penetrated in its entirety in wells <a href="javascript:void(window.open('https://factpages.sodir.no/factpages/Default.aspx?nav1=we
