Improving suggestions[edit]

I would like to improve this article. E.G. the cited article is a dead link.

As I know this article, because Prof. Urai is my teacher, I know that the cited articles does not match the topic Boudinage exactly. It deals with linear fluted structures, the Mullions!EndoMax 11:07, 16 April 2007 (UTC)

"Boudinaged marble"[edit]

The image with the legend "Boudinaged marble bed within blueschist, Samos, Greece" most likely shows a segregation quartz vein in phyllite. These are secondary vein formations, so while they are "competent" now, they were once simply absent. —Preceding unsigned comment added by A.C. Akhavan (talkcontribs) 23:33, 8 September 2009 (UTC)

It may even be a quartz-feldspar pegmatite from the image, but I agree that it's definitely not marble (dangerous though it is to do rock identification from someone else's field photo). I'll change it to "Boudinaged quartz vein" and drop a note on the image talk page. Mikenorton (talk) 08:06, 9 September 2009 (UTC)


According to my longstanding understanding, the use of "competent" in the article is backwards. (It's the less competent bed that breaks up.) — Preceding unsigned comment added by PMH232 (talkcontribs) 12:44, 28 August 2013 (UTC)

I've added another reference to show that it is the competent layer that breaks up. Mikenorton (talk) 01:44, 29 August 2013 (UTC)


Oops! The following should be ~deleted~, since "chocolate-tablet boudin" is apparently a "term of art": - - - - - - — Preceding unsigned comment added by PMH232 (talkcontribs) 13:06, 28 August 2013 (UTC)


(I (USA) have never heard of this. References to ... (how does one say this?) something that's supposed to clarify something by serving as a well-known example ... should be universally recognizable.) — Preceding unsigned comment added by PMH232 (talkcontribs) 13:00, 28 August 2013 (UTC)

This is a relatively common term in structural geology. See e.g. [1], [2]. Mikenorton (talk) 01:53, 29 August 2013 (UTC)
