The buried and well preserved Kärdla crater in Estonia (Southern Fennoscandia) (58°59Ń, 22°40É), with a diameter of approximately 4 km, was discovered in 1967. The subsurface structure of the crater has been studied by gravity anomaly measurements, aeromagnetics and by more than 300 boreholes in the crater, on the rim (“ring wall”) and in the surrounding area. Recent boreholes, reaching 800 m, have revealed that the crater is 540 m deep and has 100 m high central peak. Barely visible in the present ...

Kärdla impact crater, 4 km in diameter, was formed in the early Caradoc (Late Ordovician) in the Baltoscandian shelf sea, a sediment-starved temperate-water carbonate basin. The Upper Ordovician post-impact sediments that cover the Kärdla crater are 15–275 m thick. The crater rimwall is composed of three separate basement rises that formed islands or shoals in the Late Ordovician shelf sea and influenced the sedimentation in the surrounding area. The rises provide the means to study the shallow-water ...

The Kärdla marine impact structure (Estonia, 58°58′N, 22°46′E) was formed at 455 Ma (Upper Ordovician), in a shallow epicontinental sea some tens of kilometres from the land and erosion area. The iron-rich projectile about 200 m in diameter approached from the west at an angle of 30–45°. The impactor penetrated about 50-m-thick water layer and the sedimentary cover and exploded in the uppermost part of the crystalline basement. A complex crater, 4 km wide and about 500 m deep, with a central uplift ...

High resolution continuous seismic profiles, shot during 1990-1992 between: Sweden and Estonia, have provided new details of the Lower Paleozoic seismic strati- graphy and especially on the traceability of seismic reflectors.Combined with recent lithologic and biostratigraphic information from onshore drillings these findings make it now possible to perform stratigraphic interpretations on epoch rather than period level.The onshore core studies show distinct differences in the facial pattern of ...
