"Uncovering the World's Largest Asteroid Crater in a Small NSW Town"

Researchers from UNSW have discovered evidence for a 520km asteroid impact structure buried near Deniliquin in southern NSW, potentially making it the world’s largest known asteroid impact structure. The structure is estimated to have been created by an asteroid impact cluster around 445 million years ago, coinciding with the Late Ordovician mass extinction. The findings are based on magnetic patterns beneath the Murray Basin and geophysical data, but further physical proof is needed to support the current evidence.

Mysterious Megalith Discovered Beneath Australian Soil

Geologist Andrew Glikson's research suggests that Australia may be hiding the largest known asteroid impact structure on Earth, estimated to be over 320 miles in diameter. Known as the Deniliquin structure, it was proposed in the late 90s and recent analysis confirmed its existence. The impact likely occurred 445 million years ago, coinciding with a mass extinction event that wiped out 85% of life on Earth. Further drilling is needed to provide definitive proof of the impact, but evidence such as symmetrical ripples and radial faults supports the theory.

"Mysterious Magnetic Anomalies Suggest Massive Utah-Sized Asteroid Crater, Study Reveals"

A massive object with "magnetic anomalies" buried deep beneath the Australian outback is likely the largest asteroid crater ever found on Earth, according to a study. Known as the Deniliquin Structure, the underground object has a minimum diameter of 273 miles, surpassing the Vredefort impact structure in South Africa. Geophysical data and core samples suggest that the crater is approximately 445 million years old and may have caused a mass extinction event. The discovery adds to the 30 known craters on the Australian continent, with the oldest dating back over 1 billion years.

"Uncovering Australia's Massive Buried Asteroid Impact Structure"

Researchers have identified what they believe to be the world's largest known impact structure, buried deep in the earth in southern New South Wales, Australia. The Deniliquin structure spans up to 520 kilometers in diameter, surpassing the previously considered largest impact structure, the Vredefort impact structure in South Africa. The structure's existence is supported by geophysical data, including magnetic readings and seismic measurements. Further drilling and analysis will be needed to confirm the impact and determine its exact age, which could provide valuable insights into Earth's early history and the Late Ordovician mass extinction event.

"Unearthing Australia's Hidden Giant: The World's Largest Asteroid Impact Structure Discovered"

Researchers have identified what they believe to be the world's largest known impact structure, called the Deniliquin structure, buried deep in southern New South Wales, Australia. Spanning up to 520 kilometers in diameter, it surpasses the previously considered largest impact structure, the Vredefort impact structure in South Africa. The Deniliquin structure shows characteristics of a large impact, such as a central uplifted dome and magnetic patterns indicative of intense magnetic forces during the impact. Further drilling and analysis are needed to confirm the impact and determine its exact age, which could provide insights into Earth's early history.
