Late veneer, late accretion, and late heavy bombardment are concepts introduced by different scientific communities to address the very last stage of earth formation when the planet acquired the final bit of its mass, after the end of the core‐mantle differentiation process, and/or the giant impact that gave origin to the moon. However, the same names are used to indicate quite different processes. This chapter defines these concepts, and describes the processes that they refer to and their mutual relationships. It deals with the late veneer, as defined by the geochemical community. The chapter briefly describes the mode of formation of the earth, which leads in a natural way to define the concept of late accretion. It discusses the relationships between late veneer and late accretion. The chapter explains the issue of the delivery of volatiles to the Earth and its chronology.
