WorldYellow In detail

Veevers crater is named after Australian geologist John Veevers who used to work in this area in the 1950s. This small crater was noticed by geologists during the survey in July 1975 and they were almost certain that it has been created by meteorite.

Some years later, in August 1984 a famous couple of scientists Carolyn and Eugene Merle Shoemaker discovered several pieces of a metallic meteorite on the rims of the crater – thus the meteoritic origin of the crater was verified.

The age of the crater is not certain – but most likely less than 4 000 years. The meteorite fell in the flat desert plain between Great Sandy and Gibson Deserts. The dry desert environment has conserved the consequences of the impact very well – even the pieces of the meteorite still look rather fresh.

Crater is symmetrical, bowl-shaped, formed in Cenozoic laterites. Rim of the crater is some 20 m wide and rises approximately 1.5 m above the surrounding plain. Diameter of crater is 70 – 80 m, depth – up to 7 m. The original meteorite was some 100 – 1000 tons heavy.

This is the only known impact crater on Earth created by the very rare IIAB iron meteorite. Less than 0.5% of meteorites on Earth belong to this type. Pieces of meteorite contain exotic, very rare metallic minerals – octahedrite, schreibersite and rhabdite, kamacite, carlsbergite.

Impact craters

There are many pieces of solid matter flying around in space. And VERY frequently they fall on the surface of Earth. There are estimates that every year on Earth fall 18,000 – 84,000 meteorites larger than 10 grams: e.g. one meteorite every 6 – 30 minutes.

This category includes outstanding impact craters – detectable scars on the surface of Earth left by a body coming from outer space. The category includes also meteorites – natural objects from outer space.
