Late veneer and the origins of volatiles of Earth

Late veneer is an important paradigm in early Earth and planetary studies. It refers to the late addition of extraterrestrial materials to the Earth’s mantle after the core formation, which leads to the overabundances of highly siderophile elements in the primitive upper mantle. In this review, the origin, evolution, and expansion of the late veneer hypothesis are summarized, including some unresolved problems. I hope this review would be helpful for the new entrants to this field.
