• SFB-TRR 170 Late accretion onto terrestrial planets
The late growth history of the terrestrial planets, from the last giant collisions with planetary embryos to the subsequent late bombardment with smaller objects, is of critical importance for understanding the early chemical differentiation processes and the evolution of the terrestrial planets. The goal of this research program is to improve our current understanding of the late-accretion history of the Earth, its Moon, and other terrestrial planets from 4.5 to 3.8 billion years ago. A multidisciplinary approach will provide novel insights into the timing and rates, chemical budget, and geodynamic implications of late accretion and will constrain the physicochemical boundary conditions during this time interval.
