Changes in Earth's crust triggered an explosion of life [tr]

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.

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.

Wow! What an explosion! Put together all that intricate DNA gene stuff in correct order in whatever it was in so it could replicate itself to some day create me. Now that's an explosion!

No. 1 should read:

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 :-)

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.
