SCOL Project: Impact-Driven Chemistry and its Role in the Surface Environment of the Early Earth

We propose to conduct laboratory experiments and numerical simulations of impact processes on the early Earth. An improved understanding of impact-driven chemical processes will address questions related to the range of surface environments and chemical conditions on the early Earth (and other planets); the potential for prebiotic synthesis during impact processes and in post-impact environments; and understanding which components of the impact- cratering process aid or hinder forming favorable environments.
