Isotopes Reveal Earth's Early Exuberance – Front lawn
The prolonged and extremely violent history of Earth's accretion and following early years is directly constrained by the so-called siderophile, or iron-loving, elements, which include, among others, rhenium, platinum, osmium, and tungsten. Osmium and W isotope systematics of plume-derived ultramafic lavas called komatiites reveal the complex chemical evolution of the Earth's interior. This evolution was controlled by impacts of Moon-sized differentiated planetesimals, formation and solidification of deep magma oceans, and interaction between the metal and silicate parts of the planet.
