Why noble gases? The noble gases bear in their isotopic ratios the traces of the Earth differentiation, degassing, and long-term geodynamic evolution. When noble gases arrive at the surface, the ratios between their radiogenic and stable (primordial) isotopes hold the key to deciphering the isolation and mixing of Earth’s internal reservoirs over the course of Earth’s history.
HIDDEN
In HIDDEN we employ atomistic simulations (i) to establish the presence or not of a hidden geochemical reservoir in the deep mantle that can store noble gases, (ii) to calculate the permeability of the core-mantle boundary throughout geological time with respect to noble gases, (iii) to determine the exchanges of noble gases between the mantle and the core during the core formation, and (iv) to give estimates of fluxes of noble gases through the Earth’s mantle throughout the geological time.
