Isotopic memory of atmospheric persistence

Chemical analysis of ancient rocks reveals earliest record yet of Earth's atmosphere
Wed, 2015-01-14 10:16

Chemical analysis of some of the world’s oldest rocks, by an international team led by McGill University researchers, has provided the earliest record yet of Earth's atmosphere. The results show that the air 4 billion years ago was very similar to that more than a billion years later, when the atmosphere -- though it likely would have been lethal to oxygen-dependent humans -- supported a thriving microbial biosphere that ultimately gave rise to the diversity of life on Earth today.

Les conférences se tiendront au Town Hall, à une minute à pied du Kuujjuaq Inn!

Vive la simplicité nordique!
