Tookoonooka crater

The Tookoonooka is a large impact crater in southwestern Queensland in Australia, a meteorite caused millions of years ago. The crater is about 900 meters deep buried in the Mesozoic under the sediments of the Eromanga Basin. It is not visible at the surface.

The Tookoonooka was discovered was published by seismological investigations during a deposit exploration for oil and for the first time in 1989, According to the impact theory of impact modified quartz minerals in the crater rim, which were discovered during drilling. The diameter of the crater is estimated at 55 to 65 kilometers. The crater was formed in the Kraton Cadna - owie Formation before 123-133 million or before 115-112 million years ago. Tookoonooka is associated with numerous small oil fields.

Seismic data point to a nearby comparable structure from the same period, which is called Talundilly. Although it seems that Tookoonooka and Talundilly emerged at the same time by a meteorite, this can be no investigations with holes will not show.
