A major tool in the initial recognition and study of terrestrial impact craters,∼ 20% of which
are buried beneath postimpact sediments, is geophysics. The general geophysical character …

Fluid‐filled fractures and microcracks are the most stress sensitive component of crustal rock
and often determine the pathways and volume of crustal fluid movement. If we are to …

Only three very large, confirmed impact structures are known on Earth: the Chicxulub Crater
(Mexico), 65 Ma, ca. 180 km wide; the Sudbury Structure (Canada), 1.85 Ga, 200 km in …

An attempt is made to integrate recent continental seismic reflection, refraction, and geologic
observations into a unified scheme of craton evolution.(1) Nascent continental crust of …

Approximately 130 terrestrial hypervelocity impact craters are currently known. Due to
variations in preservation and in geologic knowledge, this sample is biased towards young …

During 1985 about 80 km of surface multichannel Seismic reflection data were collected
across the meteorite impact in the Siljan Ring area in central Sweden. The area consists …

In earlier studies, the 65‐75 km diameter Siljan impact structure in Sweden has been linked
to the Late Devonian mass extinction event. The Siljan impact event has previously been …

From a variety of seismic refraction and reflection profiling results, a new detailed Moho
depth map for the Fennoscandian part of the Baltic Shield has been compiled. A …

The gravity‐driven collapse of complex impact craters induces the mass transfer of large
rock volumes. In distal parts of a crater, inward movements dominate; whereas in the centre …

Understanding the state of stress in the earth is important for a broad range of engineering
and geological problems. To obtain the state of stress in boreholes where conditions are …
