A team of scientists from Australia and the USA carefully studied the mysterious Wolf Creek Crater, which is located in the western part Australia It turned out that this crater is not as ancient as researchers considered earlier. According to the publication Science Alert.
This crater was known to the indigenous people of Australia, and scientists learned about it thanks to a study conducted in 1947 aerial photography. The locals call it “Gandimalal”.
How and when did Wolf Creek Crater appear
Scientists have investigated the underlying rock in the area of the fall meteorite, where aluminum-26 and beryllium-10 isotopes were discovered. Experts used optical dating to calculate the time at which samples taken for study were affected explosion energy or sunlight. It was previously believed that this a crater arose about 300 thousand years ago, however a new study showed that he is a maximum of 137 thousand years.

Scientists found that a meteorite fell in western Australia reached dimensions of 15 meters, and the speed at which it crashed into surface, was equal to 17 kilometers per second. As a result This collision formed a crater with a depth of 178 meters and diameters of 892 meters. The shock was such a force that a powerful temperature impact destroyed underground rocks. Over time, the crater skidded sand, and its depth decreased to fifty meters, and in his vegetation appeared in the center.
Early research showed that similar craters arose. every 13 thousand years, and smaller craters appeared every 500 years.
ESOREITER previously talked about unusual and dangerous craters. Siberia, which were discovered from the satellite of the island of Yamal.
