Japan Just Found a Huge Rare-Earth Mineral Deposit That Can Supply The World For Centuries

Japan Just Found a Huge Rare-Earth Mineral Deposit That Can Supply The World For Centuries | Geology | Scoop.it
The newly discovered deposit is enough to "supply these metals on a semi-infinite basis to the world," the study's authors wrote in the paper. There's enough yttrium to meet the global demand for 780 years, dysprosium for 730 years, europium for 620 years, and terbium for 420 years.

Fossil tracks in the Alps help explain dinosaur evolution 

Fossil tracks in the Alps help explain dinosaur evolution  | Geology | Scoop.it
THAT the dinosaurs went out with a bang is well known. About 66m years ago a large space rock hit what is now southern Mexico. As a consequence, and with the assistance of some enormous volcanic eruptions on the other side of the planet, the terrible lizards were consigned to history. That left the world open for the rise of mammals.
