Thanks decimon. Somewhere along the line, today, I was reading about supposed shortage of nickel (geologically) that led somehow to the large oxygen component in our atmosphere. :') This looks like another bit of toil (or sniffing toil) from earthbound (and hidebound) opponents of impacts. :') |

Impact deniers. They will be dealt with, comrade, they will be dealt with. ;-)

I am interested in biogeochemistry and geobiology with the following themes:
lipid chemistry of geologically significant microbes and microbially dominated ecosystems organic and isotopic indicators of climate change, biotic evolution and mass extinction...
Why, sure. Poison belching deep sea bacteria is a way more plausible explanation. :-))
