Tectonic Features of the Hecla Hook Formation to the South of St. Jonsfjord, Vestspitsbergen
Abstract 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...

| Summary: | Abstract 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. |
