A great lecture and lengthy lecture about Archean paleoenvironments, tectonics, geology, and some paleontology is: Archean Surface Conditions Ideas in Science By Christoph Heubeck - RED18 Published on Mar 12, 2018 http://astrobiovideo.com/en/video/175 https://www.youtube.com/watch?v=yNEkQ8KV-aQ It begins: "Here is the the principal take-home take-home message. All right. We know very little about the early Earth and and therefore it's such an interesting thing to talk about. We do know a bit right. We know just enough to talk endlessly about it but we do not know enough to supply you with firm numbers that would put any issue too firmly to arrest." Yours, Paul H.
