This article incorporates text from a publication now in theI clicked on Diapir and got redirected here, but there is no mention of Diapir. What's Diapir? 67.118.118.184 00:21, 1 Feb 2005 (UTC)
I hope it's temporary that "diapir", "pluton" and "intrusive" redirect here. All these terms need own article although it's okay to write about them briefly here too. I am not sure about english geological traditions but in Estonia we see intrusive and intrusion as a slightly different things. Intrusion can be both, upward moving body of magma and solidified magmatic rock body but intrusive is only crystallized magmatic body which is not moving buoyantly anymore. Volcanology as a category also creates questions because volcanism is extrusive not intrusive phenomena. They are connected of course which makes that a complicated issue but I would not add cat. "Volcanology" here. Why is a mud volcano here is also something I don't understand. Siim 09:31, 4 August 2005 (UTC)
so its like making valccanoes... — Preceding unsigned comment added by 68.97.27.152 ( talk) 16:40, 29 November 2013 (UTC)
I have moved the diapir material to Diapir (formerly it was piercement structure, but I renamed/moved it). Geologically intrusive implies igneous - whereas diapir was used more for non-igneous material, yeah also some overlap. Anyway, I have made the terminology more consistent with petrologic and geologic usage.
Sugar Loaf (Pão de Açucar) is made up of augen gneiss, that is, a metamorphic rock originated from porphyritic granite. Therefore, it is not a plutonic rock body and the image must be deleted. Amotoki ( talk) 02:16, 23 May 2008 (UTC)
Is someone with more geological knowledge than me willing to add a section or sections – including diagrams such as a geologic cross-section – describing combination types? Particularly, I am aware that there is such a thing as a volcano/lacolith (I am not aware if there is a standard terminology to apply here), because there are two of these in the San Francisco Mountain volcanic field near Flagstaff Arizona: Elden Mountain, and Slate Mountain. These features are partly intrusive and partly extrusive – surrounding field rock layers have been bent back as in a lacolith, but apparently the layers ruptured allowing extrusion onto the surface as well. It would seem logical to include a discussion on this topic or topics here. Cluginbuhl ( talk) 00:22, 24 July 2019 (UTC)
There is a move discussion in progress on Talk:Pluton which affects this page. Please participate on that page and not in this talk page section. Thank you. — RMCD bot 07:01, 8 November 2020 (UTC)
