Para determinar cómo los elementos cruciales para el desarrollo de la vida llegaron a la Tierra, los científicos estudian los gases nobles. Actualmente, métodos mejorados traen consigo nuevos indicios a partir del criptón, el gas noble más enigmático.
Laboratory experiments show that earthquakes may have helped early life evolve in an oxygen-free world.
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
New data on ancient zircons points to a transition from stagnant lid to subduction style tectonics at 3.6 Ga ago.
How was Earth’s early magnetic field produced? New experimental results and modeling show that the energy source could not have come from exsolution of lithophile elements from the core.
