A geological survey of Western Australia has revealed relatively young Mesoproterozoic bedrock lies beneath the Nullabor.
The Mesoproterozoic Era is a geologic era that occurred from 1,600 to 1,000 million years ago. The Mesoproterozoic was the first period of Earth’s history of which a reliable geological record exists.
The bedrocks lies between two older formations – WA’s Yilgarn Craton and South Australia’s Gawler Craton, both former tectonic plates.
According to a report by ScienceNetwork WA, the seismic survey was conducted in February with geologists intending to study the structure of the Australia’s crust.
The interstate seismic survey has revealed the unique rock formation beneath the ground that may not exist anywhere else in Australia.
