[edit] Orogeny

Subduction can lead to orogeny. -FZ 16:52, 3 Aug 2004 (UTC)

[edit] images...

The top image of subduction zone is simply wrong. Too many mistakes, I remove it. Geojide 16:44, 18 September 2006 (UTC)

It does show a rough estimate of the correct rate of decent though.

would you elaborate on what those mistakes are? thanks. Lunch 18:52, 2 November 2006 (UTC)

The diagram used to illustrate subduction near the top of the article is factually incorrect. Melt produced during subduction is not derived from directly melting of the subducting slab. It is however derived from water released during dehydration of the slab during subduction, this water rises upwards into the overlying Mantle wedge and causes melting to occur there. The diagram on this article has melt forming from the slab and entering the crust or possibly lithosphere, a common mistake but one which one fail you first year geology. Here's is a link to a correct illustration http://www.calstatela.edu/faculty/acolvil/plates/subduction.jpg

However I'm not familiar with the procedures of using other peoples work on wikipedia so I'll research a little before doing anything (Climberdave 12/03/07)

The image cited is almost certainly copyrighted (and probably not by the university owner of that page) and cannot be used. If you can get it explicitly (in writing) released to the public domain, or for any use (non-commercial only is not enough), that would be great. Geologyguy 16:47, 12 March 2007 (UTC)

Would it be possible for me to create a suitable alternative diagram? (Climberdave 14/03/2006 12:00GMT)

Certainly - anything you create, you own the copyright to and can do what you want with. Just be sure you don't "copy" a copyrighted image - i.e., using the one cited above as a "go-by" would be a no-no. Cheers and thanks - Geologyguy 13:28, 14 March 2007 (UTC)

Tricky one, but I'll give it ago when I get a chance, CLimberdave
