Gas-belching volcanoes may have killed dinosaurs
Reuters on Yahoo ^ | 3/20/08 | Ben Hirschler

Posted on 03/20/2008 1:49:58 PM PDT by NormsRevenge

LONDON (Reuters) - Gas-belching volcanoes may be to blame for a series of mass extinctions over the last 545 million years, including that of the dinosaurs, new evidence suggested on Thursday.

A series of eruptions that formed the Deccan Traps in what is now India pumped huge amounts of sulfur into the atmosphere 65 million years ago, with likely devastating repercussions for the Earth's climate, scientists said.

Gigantic eruptions, forming so-called "flood basalts," are one of two leading explanations for a series of mass extinctions that have killed off species periodically throughout history.

The other theory involves asteroid impacts -- generally considered the prime suspect in the case of the extinction of dinosaurs 65 million years ago.

There have been doubts about the killing power of volcanoes because, until now, researchers have struggled to measure just how much toxic gas would have been released.

But after finding rare inclusions of glass in the Deccan rock, a British-based team has found vital preserved information about its original gas content.

Writing in the journal Science, they concluded that the massive of amounts of both sulfur and chlorine released would probably have had a "severe" environmental impact.

"It certainly bolsters the case, though it doesn't prove it," Stephen Self, formerly of Britain's Open University and now senior volcanologist with the U.S. Nuclear Regulatory Commission, said in an interview.

"There have been several major mass extinctions and most of those have, uncannily, occurred while one of these huge flood basalt provinces was being formed."

The volcanoes may have spewed 10 times as much sulfur into the atmosphere every year as humans have done recently by burning coal in power stations and through other industrial activities.

The result would have been widespread acid rain and aerosols of sulfuric acid in atmosphere, cooling the surface of the Earth and upsetting normal patterns of circulation.

Frankly, I think that they all started to believe that they were giving off too much methane, creating global warming, and decided to commit mass suicide to save the planet.

Doesn’t really matter.

Every stage of development of the Earth, from the oxygenation by algae, the era of the conifers, the era of the dinosaurs, etc,

all were for the _purpose_ of making a habital planet for human beings to thrive on and to discover the wonders of God’s universe from.

It is interesting to see how these things unfolded, though.

If the one that hit the Yucatan about the time of the demise of the dinos, created a big enough and deep enough crater, I would assume magma and gases would have been released.

I don’t know in that instance how much of a penetration into the crust much less the outer or inner mantle occurred,, but it would sure seem like stuff would come popping up and out of that general vicinity.

The Yucatan impact was 112 miles wide and 3000 ft. deep but, that event happened 330,000 yrs before the extinction of the Dinos. It’s likely a later impact effected their extinction according to National Geographic. I’m still going with the multiple cause theory.

Looking back there is one 130 million year period where no extinctions occured.

Some scientists contend that a supervolcano was about to explode, but it was plugged up just in the nick of time by an incoming asteroid.

It’s been proposed that big impacts cause volcanism on the OPPOSITE side of the earth through focusing of seismic energy there.

Very controversial though.

Well the Earth isn’t solid. If you look at it as a ball full of liquid that you shoot with a bullet, the reaction might occur anywhere on it’s surface due to it’s irregularity.

This has been proved now - they found the giant impact crater under Antarctica (off the coast) almost exactly opposite of where the massive Russia crust collapse/volcanic disaster would have been when it hit.

How about astroid strikes that caused massive volcanic activity?

I was thinking the same thing. You would think that a sufficiently massive strike would cause shock waves through the mantle that would trigger earthquakes and eruptions

The timing isn't all that clear (yet) but I wouldn't be a bit surprised to find that an impact large enough to ring the planet like a bell could trigger massive vulcanism.

I suspect magma may be somewhat thixotropic and flow to the surface much more easily under immediate post impact conditions.

I also think an impact would jar out dissolved gases and 'pump' magma towards the surface. Compare to what you see in a sealed soda bottle when you smack it one!

Worse possible scenario. Shallow water impact. Not only all the crustal damage of a dry land strike, but the instant release of massive amounts of carbon dioxide from a mile thick layer of near shore carbonates laid down as the shells of sea life. Not only the crustal damage, and CO2 release, but a huge tsunami wiping out shoreline life for thousands of miles. Not just the crustal damage, CO2 release, and tsunamis, but a global rain of red hot ejecta.

Then there's the really bad part.

The ocean rushes in and tries to fill a 100 km wide white hot crater.

Now instead of passively radiating the excess heat out into space like a dry land strike would, the crater flashes untold cubic kilometers of salt water into steam. Not only does this pretty much steam clean the entire earth's surface, it also rains salt out onto everything, so most plants can't grow even if their seeds managed to survive all the above excitement.

I believe 1/2 or more of the Yucatan crater was in water. (don’t know the depth at that time)

I’m sure what ever happened then was *worse *case* or close to it.

Interesting how they discoved the crater.

Multiple causes?

I have just finished reading “Comet” by Carl Sagan and Ann Druyan, revised 1997. It contains lots of interesting info about the behavior and size of comets and past and future damage potential for earth. We may be entering a period of more than average activity. Comets even if they are just an airy “snowball” can be seriously disasterous if they are large enough. “The Cycle of Cosmic Catastrophes”, Firestone, et al., 2006, hypothesizes a 300 mile diameter snowball crashing into what became Hudson Bay about 13,000 years ago, destroying the Clovis Indian culture, decimating the large mammal population, and precipitating the 1,000 years of cold called the Younger Dryas. This study also highlights the fact that these extraterrestrial bodies often come in groups as we saw with Shoemaker-Levy strikes on Jupiter recently.

The 34 mya Chesapeake Meteor event, with its 50 mile diameter crater, also coincided with the 60 mile diameter Popigai (sp?) crater in Siberia, the 9 mile Toms River (NJ) crater and a 10 mile crater in Spain.

Regarding the Permian extinction, this newly discovered crater at Antartica could also have occurred along with the better known Bedout crater near Australia. They both occurred enough opposite the Gigantic Siberian Trapps (4 or 5 times the volume of the Deccan) to have caused a reverberation effect through the earth.

It has also been hypothesized that there is a crater 4 or more times larger than the Yucatan crater called Shiva that was of the same time period. This crater appears to be on the West side of India, and if it exists could have been an immediate cause of the Deccan activity. For all we know a large boloid could have struck Siberia and been covered by the Siberian Trappes. Has anyone encountered any recent information about this controversial crater?

I just tried to pull up the web side listed in the Cosmic Catastrophes book. It is listed as www.cosmiccatastrophes.com, and it does NOT work.

I did find another listing referenced on the Googles page which does have interesting info: http://www.perigeezero.org/treatise/index.html

For those who are aware of the hypothesis that Lake Michigan was formed by two boloid strikes, they had a great underwater map. When I read the book it looked to me as if there could have been a smaller strike between the two larger ones, and lo and behold, there on the map is a third smaller depression between the two larger ones. I tried to transfer the map here, but that was beyond my computer skills. Someone else want to try?
