Removed the following pending a source:

Salt rocks also form by replacement of carbonate rocks by salts. A new theory of salt deposition is related to deep origin where supercritical water loss molecular polarity and capacity of dissolution of salts and then salt from brines are deposited by hydrothermal processes in deep water, mainly in rift systems. Salt rocks is frequently associated with volcanism.

Provide a reference and it can be cleaned up and re-inserted. Vsmith 02:23, 6 November 2006 (UTC)

Many solutes, one mineral?[edit]

Hi, can anyone describe how/why it is that while salt water contains many dissolved minerals, the evaporite rocks formed seem to be nearly pure beds of one substance or another? Why do evaporite minerals not match the chemical proportions of evaporated sea salt or salt water? thanks for any info you can provide. 68.121.165.9 20:15, 13 May 2007 (UTC)

I'm not an expert, but I would think each mineral would precipitate out at a specific concentration point, which (I think) would be different for each mineral. So some might precipitate out in one area as the water evaporates and leaves that area, and another mineral that tolerates a higher concentration before precipitating would be left in a different area, etc. or paerhaps they simply precipitate in layers. The key is that different minerals will have different properties of some sort that cause them to fall out of solution together, creating pure beds of each mineral as opposed to a mix.
This is just my guess. Hope it helps. --DanielCD 21:44, 13 May 2007 (UTC)

"New theory"[edit]

Removed the following:

A new theory, in development by a research group headed by Martin Hovland called "Hydrothermal salt theory", of salt formation was proposed recently. Salt originally is related to volcanic environments and hydrothermal processes involving supercritical water (loss polarity of water molecule) that can not dissolve salts and carrying out salt forming stocks. It's interesting to note that halogens such as chlorine, bromine, iodine pratically do not occur as rock forming minerals in earth surface. Then is plausible that salt origin comes from depths. Good examples are salt forming in rift zones (Red Sea, African Rift), transform zones (Dead Sea, Salton Sea), Salar Uyuni (Bolivia).

It is based on recently published material in Oil & Gas Journal, January 15, 2007 [1]. Wikipedia doensn't need to embrace such new theories quite so fast - wait a bit for some verification and testing, questioning by professionals in the field. The earlier addition of this material was sourced to Martin Hovland's website and this appears to be someone promoting his work prematurely. In addition some of the material added is simply wrong and poorly worded. For example, the halogens fluorine and chlorine do occur in surface and near surface rock forming minerals.

Not responsive. You are removing without knowledge judging as a censor like middle age times. A good chance to test present origin of salt rocks would be its mention in the Wikipedia - "The Free Encyclopedia?" In my opinion is important all people have access to new thoughts; if you remove citations based on laboratory and field researches you will kill this chance. About fluorine and chlorine, in fact, there are a lot of mineral that occur near surface rock minerals but there are much more halogens in sea water and salt pans than you know and it's more plausible that salt comes from hydrothermal deep systems related to volcanic activity. I strongly reccomend you remove vandalism in Wikipedia but not new ideas because you are walking against science evolution. Think better. —Preceding unsigned comment added by 189.60.181.114 (talk) 01:28, 24 June 2008 (UTC)

New Information[edit]

Hello,I am an undergraduate student at SUNY Potsdam, and recently did a project on Evaporites, I have some material that I thought useful. I placed it under depositional environments, and needed help integrating into what is currently written there. I believe that it will be very helpful to this page and would like to place it here without having too many problems. This was just to let you know what I was going to do, so we may work together to make this web page better for everyone. Thanks for your help. I know the citing is wrong and I am currently trying to fix it.— Preceding unsigned comment added by Garranlp193 (talkcontribs) 17:34, 13 December 2010 (UTC)

Added {{reflist}} tag to ref section to fix the problem. Vsmith (talk) 18:27, 13 December 2010 (UTC)

Thank you I appreciate the help! I hope I made the site better. — Preceding unsigned comment added by Garranlp193 (talkcontribs) 19:05, 13 December 2010 (UTC)
