The Bedout High, located on the northwestern continental margin of Australia, has emerged as a prime candidate for an end-Permian impact structure. Seismic imaging, gravity data, and the identification of melt rocks and impact breccias from drill cores located on top of Bedout are consistent with the presence of a buried impact crater. The impact breccias contain nearly pure silica glass (SiO2), fractured and shock-melted plagioclases, and spherulitic glass. The distribution of glass and… Expand

Comment on "Bedout: A Possible End-Permian Impact Crater Offshore of Northwestern Australia"
TLDR
It is suggested that the Bedout basement high, offshore Western Australia, might represent an impact structure, in view of the site's well-defined circular Bouguer anomaly and seismic reflection data indicating a possible ring syncline. Expand

The origin of the Silverpit structure, UK North Sea has been contested since its discovery on seismic data in 2002. The Silverpit structure consists of a 3 4km central zone of deformation, whichExpand

Rocks from the older complexes show a 3He/4He ratio of 14.0 times the air ratio, an initial 87Sr/86Sr ratio of 0.70483, and other geochemical characteristics similar to ocean island basalts; the later alkalic pulse shows isotopic evidence of crustal contamination. Expand
