The mysterious Jurassic volcanic region named after a cricket player

Around 100 ancient volcanoes have been found beneath Australia’s largest on shore oil and gas producing regions. The volcanoes have since been named after Australian cricket player, Shane Warne.

Around 100 ancient volcanoes have been found beneath the Cooper-Eromanga Basins. Located in the eastern corner of South Australia and the South-Western region of Queensland.

The dry barren landscape of the Cooper-Eromanga Basins is the site of around 60 years of petroleum exploration and production. The area is also home to a lesser known underground volcanic landscape.

Buried under hundred of meters of rock, the volcanoes date back to the Jurassic period, between 160M and 180M years ago.

Researchers used a multitude of scanning techniques to identify a myriad of volcanic craters as well a the deep magma chambers present in the area.

The Volcanic region is named The Warnie Volcanic Province, after the Australian cricketer Shane Warne.

From the University of Adelaide’s Australian School of Petroleum’s Professor Simon Holford, is the co-author of the study. He said: “While the majority of Earth’s volcanic activity occurs at the boundaries of tectonic plates, or under the Earth’s oceans, this ancient Jurassic world developed deep within the interior of the Australian continent.”

“wrote much of the paper during a visit to Adelaide by the Aberdeen researchers, when a fair chunk was discussed and written at Adelaide Oval during an England vs Cricket Australia XI match in November 2017…Inspired by the cricket, we thought Warnie a good name for this once fiery region.”

Associate Professor Nick Schofield, from the University of Aberdeen, works in their Department of Geology and Petroleum Geology. Schofield said:“The Cooper-Eromanga Basins have been substantially explored since the first gas discovery in 1963…This has led to a massive amount of available data from underneath the ground but the volcanics have never been properly understood in this region until now. It changes how we understand processes that have operated in Earth’s past.”
