[edit] Composition
As a chemistry nerd, I have to say that there is no way that the nitre version of caliche contains sodium iodate. Sodium iodide, perhaps, but not soium iodate. Sodium iodate is a powerful oxidizer, and to the best of my knowledge not present anywhere in nature. Sodium iodide is prevalent in sources like seawater and could most easily be found in a mineral source. The mention of iodate is probably a misquote. I will change this unless documentation can be found supporting the presence of iodate. Dormroomchemist 20:21, 1 October 2007 (UTC)
I just found something about it in literature. In the book "Mineral tolerance of animals, second revised edition, 2005" the author says, that nitrate rock contains iodine in form of iodate salts. I could also find some german books saying that iodate and not iodine is found in the nitrate rocks. why is this not possible? I always thought iodates are more stable than iodides. by the way, it might perhabs be a any form of iodate without sodium. no one in these books I read talks about "sodium" iodate. do there exist forms of iodate, which are present in nature and not so strong oxidizers?

So, in the following abstract from a sci-article you can see, that in chile iodate minerals are found. "In descending order, Chile, Japan and the United States have the largest iodine reserves. Chile produces iodine from iodate minerals while Japan and the United States produce it from sodium iodide solutions found in underground iodide solutions. Iodine is also produced from subterranean brines in Azerbaijan, Russia, Turkmenista, Indonesia and Uzbekistan. In 2005, iodine prices increased sharply to US$19 to US$23 then leveled off at US$23 to US$25." Krukowski, S.T.
