Thanks for creating this article and sorry for the long delay in welcoming you. I've added in decollement to that article and used that as the internal link, because the detachment fault article is described purely in terms of extensional tectonics. I'm trying to think of examples of detachment folding in extension, but so far haven't come up with any, but I'll keep looking. Cheers, Mikenorton (talk) 12:16, 7 July 2012 (UTC)[reply]
