Research output: Contribution to journalArticleResearchpeer-review


A total of 161 km of deep seismic profiles have been shot in the region. One profile crosses the Protogine zone in SW Sweden. Over most of the profile short, weak reflectors are seen The only area with a concentration of reflectors is in the upper two seconds between the two tectonic zones. A nearly transparent area east of the Protogine zone is interperted as a deep granite intrustion. In the Siljan impact structure where four profiles were shot, the NE part of the structure is dominated by upper crustal high amplitude reflectors. Possible causes are discussed.
