Merge material[edit]

Mudcracks resulting as part of a flood deposit on the Mancos River near Towaoc, Colorado.

The following material was left out when another article was merged here and may need to be integrated into the article.

Agreed on all points Rygel, M.C. (talk) 22:41, 19 November 2010 (UTC)

I removed the material from the talk page as it seems to have been successfully integrated except for the one picture. --DanielCD (talk) 02:01, 20 November 2010 (UTC)


I linked the word syneresis to Syneresis (chemistry). I'm not sure if they are the same thing or if this is an appropriate link. Anyone have any comments? --DanielCD (talk) 00:51, 20 November 2010 (UTC)

The link to the chemistry term (process) is probably appropriate, although syneresis cracks are a sedimentary structure formed in muddy sediment that gets exposed to liquid with a very different salinity. I have a student working on an entry for this topic, a rough draft can be previewed at: Final content should be integrated in to Wikipedia by 12/6. Rygel, M.C. (talk) 01:02, 20 November 2010 (UTC)


It might look better with some pics spread around in the article, with the leftovers in a box near the bottom of the article, as opposed to all being in one box. --DanielCD (talk) 02:31, 20 November 2010 (UTC)

Agreed! Rygel, M.C. (talk) 02:54, 20 November 2010 (UTC)

I'm kinda scratching my head over that last major edit. Did you keep track of the info that was cut or did you deem it was not of enough importance to include? --DanielCD (talk) 02:36, 20 November 2010 (UTC)

My sincerest apologies for any confusion, I think we both started to "overhaul" at the same time .. just before your 01:46 revision. I finished after you and was not sure how to deal with the "conflicting edits" message. I was working to revise and streamlined some of the content from User:AChristineS191 - I think we were going after the same things. I would be happy to compare the diffs and restore anything that I accidentally overrode. I should have done a series of smaller edits rather than a major 30-minute-long overhaul.Rygel, M.C.

File:Desiccation-cracks hg.jpg to appear as POTD soon[edit]

Hello! This is a note to let the editors of this article know that File:Desiccation-cracks hg.jpg will be appearing as picture of the day on June 23, 2011. You can view and edit the POTD blurb at Template:POTD/2011-06-23. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng {chat} 16:37, 22 June 2011 (UTC)

Mud cracks
Mudcracks in sludge, the remains of a sewage treatment plant in Kos, Greece. Mudcracks naturally form when wet, muddy sediment desiccates, causing contraction through a decrease in tensile strength. Individual cracks join up, forming a polygonal, interconnected network. These cracks may later be filled with new sediment, forming casts on the base of the overlying bed.Photo: Hannes Grobe
