Author | Topic: Where Did The (Great Flood) Water Come From And Where Did It Go? | |||||||||||||||||||||||

There is a lot of water vapor in our atmosphere, limited in extent by the tropopause, but this tropopause can vary in height according to temperatures. Colder temperatures mean higher tropopause and more water vapor in the air. A sudden increase in atmospheric temperature, as occurred during the volcanic Siberian Traps, would lower the tropopause releasing huge amounts of precipitation from the atmosphere. The seeding and air circulation caused by the volcanic activity would have contributed towards excessive rainfalls.
Thus the source of water for the flood was from the continental changes during the PT boundary, combined with precipitation from a lowered tropopause and volcanic activity, and also from the melting of the ice caps and melting of glaciation caused by the increased temperatures from the Siberian traps. The flood water most likely receded when water flowed into the great chasm when Pangea first split. Edited by mindspawn, : No reason given. Edited by mindspawn, : No reason given.

1) The tropopause is temperature sensitive and it will drop in height at low temperatures 2) Water vapor is mainly limited beneath the tropopause
It didnt necessarily occur simultaneously. The chasm can be created in the midst of a landmass and then spread and widen BEFORE reaching oceans. Thus we have a reduction in the size of the Panthalassic ocean before the water reaches the chasm. This would add to the flooding effect because of the reduced size of the ocean during the creation of the dry chasm. The moment the chasm reaches the ocean, water would start pouring in, which is consistent with records of a marine regression during the PT boundary.

I haven't got exact working. I would assume the bulk of the water came from the melting ice caps and melting glaciation and from the reduced ocean size during the break up of Pangea, and NOT the water vapor, but the water vapor levels and seeding from volcanoes could explain the extensive rainfalls, even if the rainfalls were not the bulk of the water. If you feel this is impossible, show your workings, otherwise its a possibility.
Exactly, assuming the depth of the new ocean floor is approximately the same as the depth of the ocean, which is highly likely. After the flood, waters then recede to approximately pre-flood levels. Edited by mindspawn, : No reason given.

To say it didn't happen, you would have to disprove all reasonable possibilities presented. I have presented a reasonable hypothesis if you think the hypothesis unreasonable , present your case why you think so.
I'm not following you, why the need for "extra water". I believe sea levels would have risen from the melted glaciation and melted ice caps, and also the compressed oceans from tectonic activity, with maybe a slight rainfall effect too. They would have receded when the new oceans opened up, and ice caps started re-forming. Edited by mindspawn, : No reason given.

hmmmm ok, that's your view
![]() Maybe someone else will be prepared to discuss the validity of the claim of Siberian Trap related melting of ice caps/glaciation at the end Permian/PT boundary causing rising sea levels? I do think this is on topic for the thread, which is asking for claims of where the flood waters came from. Edited by mindspawn, : No reason given.

Not at all. The PT boundary is famous for what is known as the Siberian Traps. This was a period of extreme volcanic activity in northern Russia. http://palaeoentomolog.ru/Lib/Chumakov3.pdf The continental land mass of Pangea peaked at the end Paleozoic http://www.episodes.co.in/...s/244/239-244%20Metcalfe%20.pdf The end -Permian is well known for an extensive marine transgression If anyone is interested I can show evidence for widespread mass movements of sedimentation during the PT boundary as well. I am not saying I have proved a flood at the PT boundary, just supporting a hypothesis that there were factors contributing towards a worldwide marine transgression then. Volcanic activity, melting glaciation, melting ice caps, huge landmass of Pangea established.

Completely agree. That is why my focus for the source of flooding is the melting glaciation and melting ice caps, sea levels often changed by a couple of hundred meters in ages past. Contributing factor is the expansion of the land mass to a peak at the formation of Pangea., continental masses and movements contributing towards changes in sea levels as well. As you know I've been discussing this on the "Portillo" thread, so I feel there has already been sufficient back and forth on the subject, its not as if these threads reach consensus so I don't really see the need to carry on the discussion further in yet a third thread. Those in the other thread seemed too distracted by side issues to really challenge the basic hypothesis that in fact the PT boundary is an extreme situation involving a marine transgression, marine regression and vast sediment movements. Enough evidence for a valid hypothesis already exists, sure its not proven, its an evidence based hypothesis awaiting futher proof.
