A lithium deposit discovered in a volcanic crater along the Nevada-Oregon border may hold up to 40 million metric tons of the rare metal — possibly the largest ever in the world, which could have a massive impact on the electric vehicle industry, according to a new study. The deposit hidden within the McDermitt Caldera is estimated to hold between 20 million and 40 million metric tons, which would be nearly double the current record of about 23 million metric tons found over the summer beneath...

Zealandia broke apart from the supercontinent Gondwana millions of years ago then sank; It’s hard to study an underwater landmass, but researchers say they’ve created a complete map; Studying Zealandia’s geology helps scientists understand how and why supercontinents break up. After decades of work, a team of scientists has finally completed a map of Zealandia. It’s helping them unlock the secrets of this lost continent’s mysterious past. Zealandia is sometimes call...

A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the journal Nature, have important implications for modeling climate change scenarios. Resource: phys.org...
