"A structural study of rocks of the Hecla Hook formation in the area of Forlandsundet of Vestspitsbergen reveals the presence of two B-axes. The earlier (B 1 ) trends roughly east-west and affects only the Hecla Hook formation; the later axis (B 2 ) trends roughly north-south, and affects also rocks of Carboniferous age. It is suggested that B 1 is the main 'Caledonian' axis in this area, and that B 2 and the roughly north-south 'grain' of the rocks concerned are lower Tertiary phenomena."
