A diagrammatic representation of the Earth in the Archaean showing subducted ocean floor carrying its chemical signature into the deep mantle. The signature which includes water and chlorine is preserved in melt inclusions contained within olivine and carried back up to surface within komatiite lava flows.

Ancient drop of water rewrites Earth’s history

This fossilized tree leaf, is the first of their kind to have been found in the area. Alexandre Demers-Potvin, used the samples he collected to establish that Eastern Canada would have had a warm temperate and fully humid climate during the middle of Cretaceous period.
