Seismic characterization of impact craters: A summary

Michael J. Mazur, Robert R. Stewart, Alan R. Hildebrand, Don C. Lawton, and Hans-Hendrik Westbroek

ABSTRACT

Enigmatic circular features have been observed on seismic data collected at various locations worldwide. We have examined eight seismic datasets collected within the Western Canadian Sedimentary Basin (WCSB) and other parts of the world over circular subsurface features. In these structures, we have observed many characteristics diagnostic of impact craters such as raised rims, annular synforms, terraced regions, inferred breccia infill, and large-displacement faults. All of the WCSB structures either have hydrocarbon production or production potential.
