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… 

Australian northwest margin, meteorite impact and seismic velocities: is there a connection?

The Bedout High in the Roebuck (formerly offshore Canning) Basin at the NW Australian Margin (NWAM) has recently been re-interpreted as a massive impact structure that appears to be associated with

Glikson ([ 1 ][1]) suggests that any “true” extraterrestrial impact structure should include shocked minerals (for example, quartz with planar deformation features, or PDFs), high-pressure polymorphs

GRACE gravity evidence for an impact basin in Wilkes Land, Antarctica

New details on the east Antarctic gravity field from the Gravity Recovery and Climate Experiment (GRACE) mission reveal a prominent positive free‐air gravity anomaly over a roughly 500‐km diameter

The end-Permian regression in the western Tethys: sedimentological and geochemical evidence from offshore the Persian Gulf, Iran

Detailed sedimentological and geochemical records across the Permian–Triassic boundary (PTB) in five offshore wells of the central Persian Gulf served to interpret the end-Permian sea-level change in

In pursuit of causes for the greatest mass extinction : the Permo-Triassic Boundary in the Southern Hemisphere - part II : investigating 260 million years old, meteorite-impacted sedimentary rocks in central-west Brazil

Various catastrophic and/or episodic events have been suggested to have caused the end-Permian mass extinction close to the Permo-Triassic Boundary (PTB). The theories and extinction-scenarios are

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.

Origin of the circular silverpit structure, UK North Sea : meteorite impact or salt withdrawal?

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, which

Chicxulub Crater: A possible Cretaceous/Tertiary boundary impact crater on the Yucatán Peninsula, Mexico

We suggest that a buried 180-km-diameter circular structure on the Yucatan Peninsula, Mexico, is an impact crater. Its size and shape are revealed by magnetic and gravity-field anomalies, as well as

Abstract— The 24 km diameter Ries impact crater in southern Germany is one of the most studied impact structures on Earth. The Ries impactor struck a Triassic to Upper Jurassic sedimentary sequence

Chondritic Meteorite Fragments Associated with the Permian-Triassic Boundary in Antarctica

TLDR
In one sample, the meteoritic fragments are accompanied by more abundant discrete metal grains, which are also found in an end-Permian bed at Meishan, southern China, and the implications for a suggested global impact event at the Permian-Triassic boundary are discussed.

Early and Late Alkali Igneous Pulses and a High-3He Plume Origin for the Deccan Flood Basalts

TLDR
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.
