Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

Defining the age of the Moon has proven to be an elusive task because it requires reliably
dating lunar samples using radiometric isotopic systems that record fractionation of parent …

The Earth formed by accretion of Moon-to Mars-size embryos coming from various
heliocentric distances. The isotopic nature of these bodies is unknown. However, taking …

The giant impact hypothesis remains the leading theory for lunar origin. However, current
models struggle to explain the Moon's composition and isotopic similarity with Earth. Here …

The timeline of the lunar bombardment in the first Gy of Solar System history remains
unclear. Basin-forming impacts (eg Imbrium, Orientale), occurred 3.9–3.7 Gy ago, ie 600 …

Earth and the Moon are shown here to have indistinguishable oxygen isotope ratios, with a
difference in Δ′ 17O of− 1±5 parts per million (2 standard error). On the basis of these data …

The date of the Moon-forming impact places an important constraint on Earth's origin. Lunar
age estimates range from about 30 Myr to 200 Myr after Solar System formation. Central to …

In this chapter, we present and discuss in detail current and novel advances in our
understanding of the processes that drove primordial differentiation of the Moon. This …

Earth's origins are challenging to elucidate, given the lack of surviving terrestrial geology
from the first 500 Myr of the Solar System. In this Review, we discuss breakthroughs in …

The application of Mo isotopes to study geodynamic processes is a rather new development
that has gained considerable momentum over the past few years. Its redox-sensitivity …
