	Bedout - Wikipedia, the free encyclopedia
		Bedout or Bedout High, (IPA pronunciation: [bedʉː]) is about 25 km off the northwestern coast of Australia in the Roebuck basin.
		Some scientists speculate that Bedout might be the result of a large bolide impact event that occurred around 250 million years ago; a large impact event during that time frame, incurring other factors, could account for the Permian-Triassic extinction event.
		The Bedout impact crater is also associated in time with extreme volcanism and the break-up of Pangea.

	Bedout: an end-Permian impact site? (Site not responding. Last check: 2007-11-01)
		The first evidence for an impact structure in the Bedout area was based on petroleum exploration company seismic data described in 1996 by Australian petroleum geologist J. Gorter.
		It is evident that the Bedout structure was exposed on land during parts of the Triassic and Jurassic, and significant erosion may have taken place.
		These include the overall glassy nature of the rock, the presence of feldspars with swallowtail terminations, which is indicative of very rapid crystallization, and the existence of spheroidal glass and extremely siliceous glass, both of which are consistent with impact melting and not with volcanism.

	BEDOUT ISLAND
		Browny had been to Bedout before with me on a previous trip but for Vaughan and Nugget it was a first.
		Even though the tide had turned from the high only a couple of hours earlier it was a slow and careful trip over the reef with all eyes out looking for any bommies as we headed towards the sandy beach on the eastern side of the island.
		After crossing the reef we stopped in the sandy bay on the northern tip of Bedout with the intention of throwing lures around for a bit of a play with the resident Queenies.

	Impact at Bedout: 'Smoking gun' of giant collision that nearly ended life on earth is identified
		Evidence is mounting that 251 million years ago, long before the dinosaurs dominated the Earth, a meteor the size of Mount Everest smashed into what is now northern Australia, heaving rock halfway around the globe, triggering mass volcanic eruptions, and wiping out all but about ten percent of the species on the planet.
		Simulations of a six-mile wide rock striking the area suggest a crater rim should be visible about 60 miles from the central dome, and despite the extreme age of the impact site and the rearrangement of continental plates since then, there is evidence of a rim at that distance.
		Coincidentally, the Bedout crater, at 120 miles across, is almost exactly the same size as the Chicxulub crater in the Caribbean that has been identified as the impact site of the meteorite that dealt the dinosaurs their death blow.

	deseretnews.com \| Sign of extinction: Australia crater
		A team of U.S. scientists said Thursday they believe the Bedout (pronounced Beh-DOO) crater is where a 6-mile-wide meteorite hit, triggering the Permian-Triassic extinction that erased about 90 percent of marine and 70 percent of land species.
		The melted rock filling the Bedout crater likely released soot and sulfur that polluted the atmosphere and the oceans, triggering catastrophic climate change, Becker's team suggests.
		Bedout was first identified as a crater in 1996.

		There are several lines of evidence that indicate the Bedout crater was caused by a meteor impact rather than volcanic activity.
		The scientists say the Bedout crater was caused by a 10-kilometer asteroid, similar to the one that created the Chicxulub crater in Mexico's Yucatan Peninsula.
		The grain size of the shocked quartz associated with the Bedout crater follows the same distribution pattern as Chicxulub.

		AB: The Bedout High in the Roebuck Basin at the NW Australian Margin (NWAM) appears to be a good candidate for a massive impact structure associated with the global Permian/Triassic extinction event.
		Rapid crustal thinning outboard of the Bedout High and the presence of a thick layer of magmatic underplating in the lower crust are among these features.
		Based on the geophysical, chemical and petrologic evidence, we hypothesize that the Bedout structure formed as the result` of an ET impact with Permian age rift margin basalts and continental sediment.

	EARTH SCIENCE: A POSSIBLE END-PERMIAN IMPACT CRATER
		Gorter, based on the study of a single seismic line, suggested that the Bedout ("Bedoo") High offshore of northwestern Australia might be the central uplift of a large end-Permian impact crater.
		Both wells were drilled through 3 km of marine and fluvial sediments consisting of carbonates with occasional interbeded siltstones and mudstones (Tertiary to Cretaceous) and sandstones interbeded with claystones, siltstones, and coal (Cretaceous to Triassic) before reaching a breccia (Late Permian).
		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.

		But in the past geologist John Gorter of Agip found evidence of a circular structure 200 kilometers (125 mi) in diameter called the Bedout, in currently submerged continental crust off the northwestern coast of Australia, and geologist Luann Becker, of the University of California, confirmed it, finding shocked quartz and brecciated mudstones.
		The Bedout impact crater is also associated in time with extreme volcanism and the break-up of Pangaea.

		Bedout, buried in the seafloor off Australia's northwestern coast, is 120 miles (195 km) across.
		From seismic and gravity data, the scientists believe that Bedout is about 120 miles (195 kilometers) wide — about the same size as Chicxulub.
		Like Chicxulub, Bedout also is associated in time with extreme volcanism — specifically, a massive lava outpouring known as the Siberian Traps.

		Becker and her colleagues’ interest in the site was first sparked by the work of geologist John Gorter, who in 1996 suggested that the unique geological formation of Bedout High is in fact an impact crater 200 kilometers wide.
		Once the researchers had satisfied themselves that Bedout High was indeed the site of a massive impact, the next stage was to date the event as precisely as possible.
		This pattern is hardly surprising, since the smaller granules would naturally be carried further away by the winds than the larger and heavier granules, and it served to confirm that the Chicxulub was indeed the source of the shocked quartz.
