Tookoonooka crater, Impact crater in Eromanga Basin, Australia.
Tookoonooka crater is an impact structure located in Queensland with a diameter of approximately 55 kilometers. At its center sits an uplifted dome spanning about 22 kilometers across, which shows the characteristic form that results from a major cosmic collision.
The crater formed approximately 128 million years ago when a meteorite struck the region, which was then covered by an inland sea. This collision left a lasting imprint on Earth's crust that remains visible in the landscape today.
Scientists and researchers frequently visit the site to study the geological formations and collect samples for understanding Earth's impact history.
The area has been developed for petroleum exploration, which has revealed small oil fields associated with the crater structure. Mining infrastructure exists on-site, though visitor access may be limited in some areas due to ongoing operations.
The crater contains distinctive impact melt breccias with devitrified glass fragments located about 25 kilometers southeast of the central uplift. These glass fragments give scientists important clues about the conditions during the original collision.
