Sea vs. Ocean[edit]

Wetman – I reverted your removal of the sentence about the "atlantic". I wouldn't have written that if I didn't see it. I'm not saying they're wonderful sources, I'm just saying that's what they appear to do. – Isogolem 09:03, 16 March 2006 (UTC)

Oil[edit]

In the edit of 'Tethys Sea' here, Wetman added an edit:

"Now oil geologists depend on what was once a mere postulation."

No explanation... I've removed it on merge, but only because if it looked dangly out there all alone with no support and no links. If someone wants to give it proper treatment, that'd be nice. – Isogolem 09:03, 16 March 2006 (UTC)

I feel that some discussion is needed regarding why some 70% of world oil is due to the anoxic conditions of the Tethys Seaway in what has now become the Arabian and Persian Gulf area. —Preceding unsigned comment added by 86.0.86.129 (talk) 20:32, 10 May 2008 (UTC)

Mediterrenean?[edit]

Isn't the Mediterennean Sea also a remnant of the Tethys? Nik42 05:32, 6 May 2006 (UTC)

It is quite possible you're correct. I think when I was researching, I just didn't see mention of it, so I played it safe. Isogolem 15:17, 6 May 2006 (UTC)

The Mediterrannean is indeed a remnant of the Tethys - see Hsü et al '77 etc.

The Mediterrenean can be divided into a number of tectonic plates and domains. Not all are remnants of Tethys crust, we should be careful. The Black Sea for example is sometimes seen as a remnant, but this is not undisputed. The (oceanic) crust under the western parts of the Mediterrenean (for example) is more recent than the Tethys itself, it developed when Corsica and Sardinia began moving away from Iberia. On the other hand, these pieces of oceanic crust could only grow in the setting of a closing Tethys, so it depends on your definition of a remnant. Woodwalker 20:31, 2 August 2006 (UTC)
Ah, interesting. So, geographically, we're talking about the same area, But the question of whether the underlying plate is all specifically from the Tethys plate isn't settled? Isogolem 05:18, 3 August 2006 (UTC)

I am not totally sure. There is probably some controversy. Woodwalker 11:52, 4 August 2006 (UTC)

Us Versus "These"[edit]

In the last sentence of Terminology and Subdivisions, when they say "Neither of these should be confused with the Rheic Ocean, which existed to the west of them in the Silurian era", are they referring to the Proto-Tethys oceans, or the continents of Baltica, Laurentia and Gondwana?--Mr Fink 17:01, 3 June 2007 (UTC)

The current text is indeed rather unclear. These and them refer to the Proto- and Palaeo-Tethys Oceans. The Rheic Ocean was between Baltica and Gondwana and east from Laurentia. Woodwalker 10:53, 14 June 2007 (UTC)
Is "Neither Tethys oceans should be confused with the Rheic Ocean, which existed to the west of them in the Silurian era." an acceptable rewrite?--Mr Fink 16:33, 14 June 2007 (UTC)


Historical background[edit]

About Prof. Suess and plate tectonics:

The theory of plate tectonics later disproved or overrode many parts of Suess's theory, even determining the existence of an earlier body of water called the Tethys Ocean.

What's the second clause supposed to mean? 85.8.12.78 (talk) 19:54, 26 July 2008 (UTC)

Caspian Sea?[edit]

The article states the Caspian was part of the ocean, whereas the Caspian Sea states the opposite. I think this needs some clarification, one way or t'other. -- J.P.Lon (talk) 07:58, 28 December 2008 (UTC)

At the moment I have no idea which is true. The name Tethys Ocean is often used in a broad sense though, for several ancient interconnected oceanic domains as well as the "Tethys Ocean proper". It would not surprise me if the Caspian Sea is considered by some authors to have been part of the Tethys. What I do know for sure is that it was part of the Paratethys Sea, so I replaced the reference to the Tethys with a reference to the Paratethys in the article about the Caspian Sea. The question remains open, but at least the text of one article is now correct. Woodwalker (talk) 16:24, 28 December 2008 (UTC)
I guess as the Caspian sits on continental crust, it is incorrect to state it was part of the Tethys ocean...--Kaapitone (talk) 13:11, 4 February 2013 (UTC)
Only the northern Caspian Sea sits 'firmly' on continental crust; the deeper southern part has remnants of the oceanic crust (see e.g. Crustal-scale structure of the South Caspian Basin revealed by deep seismic reflection profiling for discussion). It is reasonable to think of it as a remnant of Tethys Ocean. Szczureq (talk) 12:29, 15 January 2014 (UTC)

Update[edit]

The article needs a clean up. Paleo-Tethys Ocean, Proto-Tethys Ocean, Neotethys Ocean and Paratethys Sea articles should be in harmony with (Stampfli, Gérard. "Reconstructions paléotectoniques globales". Université de Lausanne. ) and (Stampfli, G.M.; Borel, G.D. (2004). "The TRANSMED Transects in Space and Time: Constraints on the Paleotectonic Evolution of the Mediterranean Domain". In Cavazza W., Roure F., Spakman W., Stampfli G.M., Ziegler P.
