Scientists Find Signs of Meteor Crash That Led to Extinctions in Era Before DinosaursDr. Becker, Dr. Poreda and their colleagues had previously found buckyballs at an impact crater in Sudbury, Canada, and in two meteorites. They have also found buckyballs containing similar types of gases in sediments dating from the dinosaur extinctions.

In the experiments, the scientists extracted buckyballs -- not just the typical sphere consisting of 60 carbon atoms, but also larger versions with up to 160 atoms -- from the sediments with organic solvents.
They then opened the buckyballs to release the helium and argon inside them. The nuclei of most helium atoms consist of two protons and two neutrons. A few -- one out of 700,000 helium atoms in the atmosphere -- are a lighter version, with only one neutron. For the helium in the buckyballs, a much larger fraction -- one out of 5,000 -- was the lighter version, similar to the ratio produced by fusion in stars.
The argon indicated a similar story, with low concentrations of a version that is commonly produced on Earth from the radioactive decay of potassium.
"I think the argon isotope ratio measurement is very convincing," said Dr. Kenneth A. Farley, a professor of geochemistry at the California Institute of Technology. "That's very hard to understand if it's not extraterrestrial."
Actually, the Mount St. Helens eruption produced an instant coal field out of the forrest below the volcano.

Interesting, I didn’t know that. Is it coal or Charcoal? Two different processes as far as I remember.
Do the carbonized trees have the dense structure of coal? And what grade are they comparable too, anthracite or lignite? And do you think they would worth being mined?
. After listening to years of talk radio at night I know for a fact that advertising announcers must have speech defects or at least odd quirks in pronunciation in order to be hired. Something analogous to that may work in the newspaper business, too.
Really? I have to buy your song to hear it?
Wow. Global coaling.
If only the great messiah Obama was there to stop it. B-P
According to the show “How the Earth was Made”, the massive fissure eruption that split open the earth’s crust caused the coal fires underground. It lasted for 20 million years and the earth was essentially dead for 25 million years after that. It created the Steppes in Siberia.

I see it all the time, epecially on Foxnews.com. They let the spell checker replace words that don't fit and then there is no such thing as proof reading anymore to make sure the story makes sense. There are no longer the requisite answers to Who, What, When, Why, How in news stories.
Wait, wait, wait. Environmentalists are always trying to stop everything and anything from ‘extinction’ in a bid to save the planet and its biodiversity.
You mean to tell me that a massive extinction occurred and Gaia survived?
If you start thinking logically you’ll mess up all their science and then where would all that funding go?
I was curious about that too, so checked some dates. The Carboniferous started around 350 million years ago, and ended 50 million years later, so there would have been 50-100 million years for the coal to have formed from the vegetation.
Didn’t you mean Centralia ping?
I read a while back where all the periods overlap and things that supposed to have happened in one era happened in another.
Many of the earth’s coal beds were laid down during the Missippian and Pennsylvanian periods which preceeded the Permian by many millions of years. The Gread Dying was at the end of the Permian and followed by the Triassic.
My hypothesis is that a giant meteor/asteroid struck in Siberia, driving down into a magma pool and setting off the formation of the Siberian Trapps, could also have set fire to coal beds. Now, everybody happy?? At any rate, Merry Christmas and Happy New Year, Catastrophism pingees and special thanks to SC for all your hard work.
