An association of organic walled microfossils is cited that gives precise details of the biostratigraphic type of this formation.

Vidal, 1976, let the formation be included in an age similar to the upper part of the lower Vendian-upper Vendian of the North-Atlantic region. B. faveolata is a dominant species in the Varangenian glacial epoch of great world-wide extension (Vidal G. et Knoll H. 1982), so the unit probably has a middle Vendian age (Varangenian).
