New Suspect in 'Great Dying': Massive Prehistoric Coal Explosion
Live Science ^ | December 22, 2011 | Jennifer Welsh

Posted on 12/22/2011 11:59:36 AM PST by decimon

A great explosive burning of coal set fire and made molten by lava bubbling from the Earth's mantle , looking akin to Kuwait's giant oil fires but lasting anywhere from centuries to millennia, could have been the cause of the world's most-devastating mass extinction, new research suggests.

The event, called the Great Dying, occurred 250 million years ago, at the end of the Permian period. "The Great Dying was the biggest of all the mass extinctions," said study researcher Darcy Ogden of the Scripps Institution of Oceanography in San Diego. "Estimates suggest up to 96 percent of all marine species and 70 percent of all land species were lost."

Researchers still debate the cause of this mass-extinction event, implicating everything from asteroids to volcanic eruptions to a decrease of the oxygen in the atmosphere.

Did Jennifer go to journalism school to write sentences this contorted or did it just come naturally to her? Can coal become molten or does it just burn?

A great explosive burning of coal set fire and made molten by lava bubbling from the Earth’s mantle , looking akin to Kuwait’s giant oil fires but lasting anywhere from centuries to millennia, could have been the cause of the world’s most-devastating mass extinction, new research suggests.”

Is it just me seeing this or have reporters generally lost the ability to compose sentences and spell correctly?

As for the theory, who cares? This announcement simply looks like another tenure seeking prof pimping for grants.

Lots of speculation and little citation of evidence in the article.

Maybe I've just gotten too cynical, but I suspect this is intended as some kind of support for EPA's determination to shut down the coal fired power industry.

I suppose The Not So Great Dying was the second-largest of all the mass extinctions, then.

So coal had to have been formed more than 250 million years ago, like millions of years before the 250 million years ago. Takes awhile to form coal from vegetation.

Except of course that the direct toxic output of volcanoes is orders of magnitude greater than any coal fire they might ignite regardless of duration.

Permian-Triassic Impact
by Phillip F. Schewe and Ben Stein
Physics News Update
Number 106 (Story #2), December 14, 1992
An asteroid impact may have caused the mass extinction that occurred at the boundary between the Permian and Triassic periods 250 million years ago, said Michael Rampino of NYU at the AGU meeting. He asserted that he has found evidence---in the form of gravity anomalies and certain rock deposits---for such an impact in the South Atlantic, in an area where, many scientists believe, South America, Africa, and other land masses fit together in the primordial supercontinent called Gondwanaland. Rampino claims that the gradual breakup of Gondwanaland into present-day continents may have been initiated by the catastrophic impact. Another scientist at the meeting, Verne Oberbeck of NASA/Ames also believes an impact may have sundered Gondwanaland and that, in general, impacts should be given more credit for shaping earlier Earth geology. In particular, he believes that the small rock sediments called tillites, usually thought to result from the grinding and plowing action of glaciers, may in part be debris from impacts. Consequently, Oberbeck suggested, there might have been fewer glacial periods than is usually believed. Rampino went so far as to say that all tillites are of impact origin. Unlike the theory that describes the KT (Cretaceous-Tertiary) catastrophe 65 million years ago (when the dinosaurs became extinct) in terms of an asteroid impact, the notion that the PT catastrophe was caused by an impact or that tillites result from impacts is anything but a majority opinion; indeed, many scientists at the meeting were skeptical about Rampino's and Oberbeck's ideas. Thomas Crowley of the Applied Research Corp., a paleo-climatologist, said that his reaction to the proposed impact origin of tillites was one of "considerable disbelief, bordering on incredulity." For one thing, he said, tillite deposits are too extensive over time and physical extent to have been caused by an impact.

Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology. The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world’s forests had been wiped out. This would explain how the organisms, which are known as Reduviasporonites, were able to proliferate across the planet... By analysing the carbon and nitrogen content of the fossilised remains of the microscopic organisms, the scientists identified them as a type of wood-rotting fungus that would have lived inside dead trees... Geological records show that the Earth experienced a global catastrophe during this period... Up to 96 per cent of all marine species and 70 per cent of land species became extinct... The team reached their conclusions by analysing the carbon and nitrogen content of Reduviasporonites using a High Sensitivity Mass Spectrometer and comparing the results with those from modern fungi. They discovered that Reduviasporonites and modern fungi show similar chemical characteristics. In the future, the team plan to carry out further comparisons between Reduviasporonites and potential counterparts among modern fungi, which they hope will provide further clues about how Reduviasporonites lived.

My question is simple, Where did the plant matter for the coal come from? As I understand it, it takes massive amounts of plant matter being laid down over millenia and then being covered by soil and rock and then compressed to make coal.

On the other hand it could have been massive peat bog fires which can be VERY smoky and last for years.

In any case, it’s a theory and to prove it one way or another is going to take a lot of research which in turn needs massive grants to fund the researchers. Which I suspect is the real reason for the theory in the first place.

Scientists Find Signs of Meteor Crash That Led to Extinctions in Era Before Dinosaurs
by Kenneth Chang
February 23, 2001
Dr. 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."

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.

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?

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.

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.

Haven’t been out to research, yet will do when have time ... remembering those three bluish things coming in from the south toward the southern hemisphere due to arrive in late 2012. Has this been proved a hoax? Had read some interesting info early on about six months ago, and have not researched since. If anything is found (when checking) will post a link or two.
