Magma 'conveyor belt' fuelled world's longest erupting supervolcanoes

International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active—erupting for 30 million years—fuelled by a constantly moving conveyor belt of magma.

It's believed this magma conveyor belt, created by shifts in the seabed, continuously made space available for the molten rock to flow for millions of years, beginning around 120 million years ago.

Research lead Qiang Jiang, a Ph.D. candidate from Curtin's School of Earth and Planetary Sciences, said the studied volcanoes were in the Kerguelen Plateau, located in the Indian Ocean, about 3,000 kilometers south west of Fremantle, Western Australia.

Co-researcher Dr. Hugo Olierook, also from Curtin's School of Earth and Planetary Sciences, explained such a long eruption duration requires very peculiar geological conditions.

Research co-author, Professor Fred Jourdan, Director of the Western Australia Argon Isotope Facility at Curtin University, said the team used an argon-argon dating technique to date the lava flows, by analyzing a range of black basaltic rocks taken from the bottom of the sea floor.

I am rooting for the Yellowstone Caldera to erupt right about now.

Roman Polanski did the same, pretty much. Except his technique wasn't argon-argon.

It’s believed[by whom?] this magma conveyor belt, created by shifts in the seabed, continuously made space available for the molten rock to flow for millions of years, beginning around 120 million years ago …
So their “magma conveyor belt” is like Stephanie Rawlings-Blake? It gave space to the magma flows so it could destroy once erupted onto the surface?

You will die from an unbelieveable Ice Age.

The Ice Age sounds more believable, honest, and humane than the democrat party’s China Joe.

Perhaps I'll move close by for a quick death, if Kamala-lala takes over the White House. At least the Chinese troops on Taiwan will die too.

That would lead to one heckuva climate change. Humanity need not apply for the job.
