Very fun and interesting paper. I was intrigued by the sudden increase in metal concentrations seen during some of the events. Any explanations for the increase that don't require heavy industry?
My guess without tech is meteor bombardment. High metal content meteors vaporizing on impact could alter the metal concentrations.
