Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.
Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.
Scientists have analysed lavas drilled from deep under the South Atlantic Ocean to understand how much CO 2 is captured within the rocks due to reactions between the rocks and ocean.
The research, led by the University of Southampton, found that piles of lava rubble, formed due to erosion of seafloor mountains, form geological sponges for CO 2 .
