A Holocene age was considered reasonably probable for all the young volcanoes of Spitsbergen by Semevskii (1965), but more detailed glacial and volcanic stratigraphy indicates that Halvdan is an eroded diatreme probably older than Sverrefjell, which is thought to be between 100,000 and 250,000 year old (Skjelkvale et al., 1989).
