Content Suggestion[edit]

Is it possible to add a section to Xray diffraction methods on clay minerals? I am still doing research on it and couldn't help.

It does sound a good idea - there are methods used for XRD for clays that are not needed for other minerals. I'll look it up and see what I can do, but IIRC the basic issue is that for powders you concentrate on the interlayer spacing that gives a strong low theta peak and use this for identification.

Added information on nontronite[edit]

Hi fellow clay people. I've added a bit on the smectite (hydrous phyllosilicate) nontronite.

Given the level of technical knowledge you have regarding the various compositions of clay, I'd greatly appreciate some discussion on the creation of tile from clay, topsoil, sand, and water and how this mixture, after drying and high temperature wood firing (+/-2,000 degrees F), becomes hardened tile.Barronica 04:31, 27 February 2007 (UTC)

clay and mica structures[edit]

The statement: "Clays have structures similar to the micas and therefore form flat hexagonal sheets." does not make sense. The statement should say that it is because clay minerals "form flat hexagonal sheets" that they are similar to micas.

Klein and Dutrow (23rd edition of the manual of Mineral Science) state that the unit of the clay minerals is Si2O5, not what is stated in the article. —Preceding unsigned comment added by The-prospector (talkcontribs) 04:14, 19 November 2009 (UTC)

meaningless piece of wisdom[edit]

"have been useful to humans since ancient times in agriculture " - does this actually mean anything? human use of basicly all soils (depending on what is available locally) is well known and hardly specific to clay.80.99.38.199 (talk) 18:42, 17 September 2017 (UTC).
