Besides delivering plausible prebiotic feedstock molecules and high-energy initiators{,} extraterrestrial impacts could also affect the process of abiogenesis by altering the early Earth{'}s geological environment in which primitive life was conceived. We show that iron-rich smectites formed by reprocessing of basalts due to the residual post-impact heat could catalyze the synthesis and accumulation of important prebiotic building blocks such as nucleobases{,} amino acids and urea.

Abstract
Besides delivering plausible prebiotic feedstock molecules and high-energy initiators{,} extraterrestrial impacts could also affect the process of abiogenesis by altering the early Earth{'}s geological environment in which primitive life was conceived. We show that iron-rich smectites formed by reprocessing of basalts due to the residual post-impact heat could catalyze the synthesis and accumulation of important prebiotic building blocks such as nucleobases{,} amino acids and urea.File in questo prodotto:
