The decay of formerly live 182Hf with a half-life of 9 Myr results in variations in the abundance of 182W in early solar system objects. Here we demonstrate that major excesses in 182W in some lunar samples are the results ...

The accretion and early differentiation of the Earth is the starting point of earth history. The abundances of metal-seeking (siderophile) elements in the mantle are a powerful probe of those events. It has long been known ...

There is a long-standing hypothesis that the last fraction of the lunar magma ocean crystallized into a layer of dense, Ti-rich cumulate minerals at shallow depths (~100 km) early in the moon's history. Many questions ...

The reasons for the similarity of the depleted abundances of V, Cr and Mn in the mantles of the Earth and Moon, which may throw light on the origin of the Moon, have been controversial. In order to test if a single-stage ...
