A Vast, Untapped Source of Lithium Has Just Been Found in The US
"#Pennsylvania sits on a vein of sedimentary rock known as the Marcellus Shale, which is rich in natural gas. The geological foundation was deposited almost 400 million years ago by volcanic activity, and it contains #lithium from volcanic ash.
Mackey and his colleagues have now found that when wastewater is dredged up from the deep by #fracking activities, it contains an astonishing amount of lithium."
