Volcanic eruptions in India, not meteorite, killed dinosaurs

Dec 9, 2012 | Posted by: roboblogger | Full story: Newkerala.com

Volcanic activity from the Deccan Traps in India, not a meteorite impact, may have killed the dinosaurs, according to a new study.

Did not die because of global warming they died because a space rock hoit earth which cause volcanic eruption, and fire which the rock also caused alot of dust to block the sun and cause a massive ice age which some how killed the plants, which starved to death herbivores and no herbivores no carnivores,also the fire destroyed many of their habitats.And the climate changed after the ice age killing the remaining dinosaurs, global warming had nothing to do with it at all you idiots.How old are you guys 3.
There are evidence out there that can disprove this theory Volcanism is already happening before the KT event there are no evidence of a global fire, this theory was based on soot which was found all over the world in the KT boundary but the problem with soot is that it can be blown hundreds of miles away, do scientists search for a clearer conclusive evidence, Charcoal and to their amazement there are almost none. The ice age if it did happen would've killed all non-avian dinosaurs.
Well an asteroid did hit the Earth 65 million years ago but how can you know that it was responsible, You seems very confident while providing no evidence.

lol talking without evidence is fiction which shouldn't be considered or taken seriously, you've never provide ANY evidence have you?(or maybe that there're no evidence to provide anyway)

Therefore it didn't happen since no one has evidence.

Just go watch the BBC documentary called "what really killed the dinosaurs" it explained very well the most recent information.

Asteroid was a mite too small to affect earth's orbit (the Earth is a big place and it weighs a hell of a lot more than a leftover space rock).

The seismic shock was large enough to be felt globally. It would have broken every megathrus on Earth @ that time. The resulting rebound/ long duration, mercalli X quakes (2004,S.Andaman arc, 2010,Central Chile arc, & 2011 Tohoku Japan being examples)... would have relaxed all of the tectonic plates on Earth. The result would definitely have been large tsunami but open ocean life would merely have felt a bump, and continents even then were high enough above sea level to have a large sector above the typical 150m max height of a range based tsunami. The Chixculub crater itself would have generated a much bigger local tsunami but decay from a crater is radial whereas decay of an arc tsunami is a sector of a much larger circle. The Chixculub tsunami would have been the size of a range r/lx tsunami when it impacted distant basin coastlines.
As for the global earthquakes, the induced r/lx events would have lasted between 10 minutes to 1/2 hour depending on the type (backarc basins lasting longest), the impact reverb would have shifted to very long wavelength by that time so everything afterward would be a classical aftershock sequence typical of Tohoku 2011 (Japan).

The more important effect with the chixculub crater itself would be the fact that the plasma fountain rebounding out into space would impart a radial force caused by its expansion and would be slowed by encounter with atoms. The density and atomic mass of the atoms the plasma ball encounters would dictate the rate of slowing...
The result is a very rapid tangential blast through the atmosphere which would be infilled by cooling plasma and rebounding slower rock fragments kicked out by the plasma ball in the rock it impacted. The radial blast wave would sweep the area struck by the slower chixculub tsunami zone clean. On average the crater produced is 12-15* the size of the impactor (rock). In the atmosphere the air crater would sweep out approximately 10-20* that diameter before lifting off from the surface forming a loud and hot warm front; (ouch).
The crater generated tsunami is a minor feature at that point.

For volcanism...

There would only have been ONE induced eruption as a result of the chixculub impact (if the molten rock flooring the crater is discounted). This would be the Eruption of the magma pool under the Deccan accumulated in a disc at the base of the crust since the last event. This would have erupted through the fracture caused by the impact induced r/lx which relaxed the indian part of the indo/australasian plate.
All other r/lx merely induces fractures parallel to island arcs that fill @ depth with magma from the base magma discs under island arcs. These erupt later via compression tectonics (years to millenia). The same r/lx will allow advancing plutons to invade the crust but they would unroof in decades to milennia depending on the height in the crust @ the time. An induced eruption there would have erupted during the next r/lx @ that island arc (as with Toba) forming a sillar.

Oops.

Almost forgot the acid rain.

Chixculub landed on a carbonate platform with evaporites.

The result would have been a case of 6 of one and a half dozen of the other. Carbonate platforms are mostly CaCO3 which would have been turned to plasma @ impact producing individual atoms when condensing, the same is true of the evaporite content (CaSO4 + a certain amount of H2O), and then of course there is the composition of the asteroid (mostly rock and some metal), and the crust underlying the platform, A thin skin of sediment overlying metasediments, tonalite granitoids and underlain by eclogite of largely basaltic composition. In all cases this would have been impactr mobilised & ionised without the requirement for a magma & magmatic gas.

All of this + fragments of plasma impact mobilised crater wall & interior rock fragments at sizes ranging from a few atoms to chunks a few hundred metres across would have been incorporated into the plume.

The CO2 content would have been high, the SO2 content would have been high, but the metal content would also heve been high, and initially, the metal component would have come down worldwide in ballistic orbit and impacted the uper atmosphere as an ion trail.

The result in the upper atmosphere would be dust composed of highly alkaline metal oxides (chiefly Ca, Mg Na, K and relatively inert Si, Al & Fe), which would have mopped up a lot of the CO2 and SO2 (+ Cl from seawater) in the plume from Chixculub itself and also from the subsequent volcanism.

The resulting mud rain would have been relatively neutral to slightly alkaline as a lot of SO2 would have arrived later after the 6 month darkness phase when the induced Deccan basalt outgassing reached the upper atmosphere. There it would have met the rain of condensed metal oxides produced by the seep up of the dust in orbit phase which would have removed the SO2 rather quickly.

Also note that volatile elements swept up in the chixculub plasma plume would have been lost if they remained relatively electrically neutral. They would have been vapour phase in vacuum and swept out by the solar wind. Volatile element ions such as nonmetals (C, N, O, S, F, Cl, H etc), would only be retained if they were captured as ions in the van allen belts and they would have come down in Aurorae directly on top of the climate mode#3 rainbelt during the "time of darkness" stage adding to the neutrality of the metal rich mud rain.

This process would ensure that the "dust in orbit stage was rich in nonvolatile metals and would be alkaline in composition, sweeping out the acid effects of any SO2 released by the induced Deccan eruption.

This relatively neutral rainfall is why the detritivores & their predators survived so well on land. Handy for their descendants I suppose...

I think that would do.

Almost forgot. The Chixculub impact would have resulted in a net loss of voltile elements such as N2, CO2, SO2, and H2O, The H2O would largely have come back as protons captured from the solar wind via the van allen belts and Aurorae reacting with O in the upper atmosphere (an ongoing process).

I do my best.

I would advise against attempting to demonstrate how big & hard the earth is by personally impacting it though.(It does hurt).

I watched What really happened to the dinosaurs, i saw the evidence and i am afraid i have to say, those scientists are dead wrong.I mean there was a ice age, amphibians survived the same way sharks and mega crocs in those days they were huge frogs so they are smaller today, and there's your answer.Why are people idiots!!!!!

Yes scientist correct errors to discover more errors that show their corrected errors need to be corrected. Because people have a different opinion of yours it makes them idiots? So what are you?

We talked about this over at DH. I said that if volcanoes did cause (most of) the dinosaurs to go extinct, it would likely be part of the asteroid. asteroid hits, if given enough pressure, can make the Earth's insides to cause a ruckus with also some poison gas.

The dominant of fern spores does suggest something killed off all plants, frogs no matter how big are affected by cold climate because that doesn't change the fact that they're cold blooded.

I'm not getting opinions, i'm getting answers(which are wrong)And i gave a answer(which is right).The newest thing you see on discovery,history or bbc chanels you people believe, make up your mind.

And isn't there also a video that proves one asteroid hit earth, that there was massive fires and a deep freeze to kill the dinosaurs.What really happened to the dinosaurs video, is a new video of what might happened to the dinosaurs.The one astroid hit earth video proves as much evidence of what really happened to the dinosaurs and that video came out before what really happened to the dinosaurs,so the more new evidence is what you believe.

Do you people realize how much i know about dinosaurs.
