In the state of Western Australia sits the famous Wolfe Creek crater, the aftermath of a 14,tonne meteorite crashing into Earth thousands of years ago.
A new study now claims the impact happened far more recently than we suspected, prompting a rethink on how often giant space rocks. Researchers have discovered two previously unknown massive meteorite craters on Earth, the most recent estimated to have been produced by an impact onlyyears ago.
The craters – one in Western Australia and the other in Nicaragua – are revealed in a pair of papers published in the journal Meteoritics and Planetary Science.
In one sense, the Australian meteorite. CRETACEOUS rocks cover two areas of abooo and square miles respectively along or near the west coast of Western Australia. In the larger of these areas, known as the North West basin, the Cretaceous has a thickness of about 2, feet and consists of a lower series (Albian) of mud- stones, shales, siltstones, and cherts; and a11 Cited by: 1.

AUSTRALIA’S RICH geology makes it the perfect place to develop a love of collecting minerals, rocks and gemstones. Famed locations such as Lightning Ridge, Cobber Pedy and Broken Hill have, for over a century, provided big yields for even the most amateur fossicker.

Meteorite Identification: The Magnet Test. Meteorites are divided into three basic groups: irons, stones, and stony-irons. Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test.

Australian meteorite craters are ancient In contrast to the relatively young craters at Henbury and Wolfe Creek, some of Australia’s craters may date back as far as two billion years. “When you get that far back you start to lose the record,” says Dr Alex Bevan, curator of mineralogy and meteoritics at the Western Australian Museum.
The size of an impact crater mainly depends on the dimensions, density and speed of the meteorite. There are many known impact craters in Australia, such as Wolfe Creek in the Kimberly, and Gosses Bluff near Alice Springs. We also know of craters that are now buried under layers of recent sedimentary rocks, such as Woodleigh, Western Australia.
Meteorite impacts in Western Australia There are over a dozen impact craters or old eroded and buried impact sites referred to as ‘impact structures’ known in Western Australia.
Most are not easily seen to the untrained eye, but some form remarkable geological features. Traces of Catastrophe book from Lunar and Planetary Institute - comprehensive reference on impact crater science Notes Edit ^ Bevan, Alex. and Ken McNamara () Australia's meteorite craters Welshpool, W.

In only three minerals had been identified in meteorites. But beginning in the s when only 40–50 minerals were known. "A lot of meteorites have got traces of water in them, as well as trace amounts of salt minerals," Dr Towner said.
"The problem is when a rock falls onto the Earth and spends months or years here. The ultra-rare mineral known as reidite was found by Curtin University researchers in the long buried Woodleigh Crater near Shark Bay, Western Australia, about km.

In Australia there are thirty-six crater-shaped structures, ranging from tens of metres to tens of kilometres in diameter, which are recognised to varying degrees of certainty as having been formed by giant meteorite : Alex Bevan, Ken McNamara.

The meteorite, called Bunburra Rockhole, is a melted basalt, which is the size of a cricket ball, he says. Zebra Rock is a strange patterned silt stone unique to the Ranford formation in the Kununurra district in the East Kimberley region of Western Australia.
Some of the many other lapidary rocks from Australia include: rhodonite, print stone, chrysoprase, crazy lace agate, peanut wood, Queensland agates, and Queensland petrified woods.
