University of British Columbia (UBC) geologist Matthijs Smit and research partner Klaus Mezger believe they have been able to show how the disappearance of a mineral called olivine from the Earth's crust led to an explosion of biological life.
Earth's early atmosphere and oceans were devoid of free oxygen, even though tiny cyanobacteria were producing the gas as a byproduct of photosynthesis.
Then, about 2.4 billion years ago, oxygen in the atmosphere suddenly increased by about 10,000 times in just 200 million years.

Ah, but ...

There is a green beach made up of olivine on the big Island of Hawaii. Hard to get to...but quite remarkable.
So now the question becomes, what caused olivine to disappear? Sounds like divine intervention to me.
Olivine weathers rapidly so when the composition of the crust changed as plate tectonics began, the crust became more stable and light silica rocks increasingly became the content of the crust (granite—72 percent silica on average). There were changes in magma composition as well.
Bwahahahaha! Got what you are doing here, but you omit:
The Goths, after besieging and taking Rome, broke into the following 10 kingdoms.
1. Vandalsand Alans in Spain and Africa
2. Suevians in Spain
3. The Visigoths
4. Alans in Gallia
5. The Burgundians
6. The Franks
7. The Britains
8. The Hunns
9. The Lombards
10. The Ravenna
Who knew NFL went back that far? :)
No. 1 should read:
1. Vandals and Alans in Spain and Africa
That’s where the oxygen went as olivine degrades quickly and there was little olivine brought to the surface when the crust was increasingly composed of granite. Oxygen was not taken out of the atmosphere in as great an amount as earlier. There is still plenty of olivine in the mantle.
True! And I heard the Lombard’s took a knee when the Roman anthem was played :-)
... and that’s how we got the Lombardi Trophy.
Oh, please! I can’t laugh any harder.
Bwahahahahahahahaha.
Kaperinchic,or whatever his name is must have taken Lomard(i) 101 in his ethnic/ethics courses.
He must have passed on the Emily Post Etiquette 101 :-)
LOL. A steroid junkie, an anorexic, and a one eyed spinach addict with elephantitis on his forearms and lower legs. That was a very bizarre cartoon.
Wow, beautiful.
“the disappearance of a mineral called olivine from the Earth’s crust led to an explosion of biological life.”
Wow, what are the odds?
Trump’s fault.
