The Geological Mystery of Australia’s Forgotten Volcanoes
Ninety million years ago, Victoria, Australia erupted after more than 200 million years of silence. This blog dives into the story behind the mysterious Older Volcanics Province — the ancient eruptions that transformed southeastern Australia and marked the breakup of Gondwana. Discover how the opening of the Tasman Sea, continental rifting, and decompression melting deep in the Earth’s mantle triggered Victoria’s fiery awakening, and why this long-extinct volcanic province still matters to Australian geology today.
