Auroral Belts as Magnetically Localized Reactors for Prebiotic Chemistry on Early Earth

O, together with minor reduced gases. In contrast to broadly distributed energy inputs, auroral activity could have repeatedly supplied reactive compounds to restricted polar environments, where subsequent deposition and freeze-thaw concentration may have promoted further chemical evolution. The hypothesis yields several falsifiable predictions that distinguish magnetically localized particle-driven chemistry from ultraviolet- or lightning-dominated scenarios. If valid, planetary magnetic fields may have played an active role in spatially organizing chemical evolution on the early Earth and may also influence chemically favorable environments on other magnetized worlds.
