Thanks for the ping, w.

t, very interesting, and likely closer to the mark.

I think it’s important to emphasize granite cooling and crystalizations as “plutonic” structures at depth rather than volcanic material extruded onto the surface which was more my initial impression from the article.

My God (really!), geo-biology is such an amazing field.

Going back a bit to abiogenesis, you might find Robert Hazen’s “Genesis: The Scientific Quest For Life’s Origin” an interesting read. I sure did.

Best....
