Mineral Resources in Deserts - USGS
Ground water leaches ore minerals and redeposits them in zones near the water table. This leaching process concentrates these minerals as ore that can be mined. Of the 15 major types of mineral deposits in the Western Hemisphere formed by action of ground water, 13 occur in deserts.

Iodine - Wikipedia
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.However, it readily sublimes with gentle heat, resulting in a widespread misconception even ...

Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution). The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma.
Iodine (I): Properties & Uses – StudiousGuy
The only iodine obtained from minerals has been a by-product of the processing of nitrate ore in Chile. The other natural source of iodine is a brine of natural gas and oil. During the 19th century, caliche was the major source of iodine throughout the world, whereas, brines of natural gas and oils are considered a more economic source of iodine since the early 20th century.

Iodine - Essential Chemical Industry
(b) From nitrate ores. In Chile, iodine occurs in nitrate deposits as iodate ions (IO 3-). The ore contains approximately 95% sodium nitrate and 5% sodium iodate, NaIO 3. After the removal of sodium nitrate by crystallization, the crushed ore is leached with hot water. The clear solution, in which the iodate ions accumulate, is run off and cooled.

The geochemistry of iodine — a review | SpringerLink
Iodine has long been recognised as an important element environmentally. Despite this there are many gaps in our knowledge of its geochemistry and even where information is available much of this is based on old data which, in the light of recent data, are suspect.Iodine forms few independent minerals and is unlikely to enter most rock-forming minerals. In igneous rocks its concentration is ...
Evidence for the chalcophile nature of iodine - ScienceDirect
High values of iodine have been found in some ore minerals and sulphide-containing carbonatites, suggesting a chalcophile nature. On the evidence of cold-water-soluble iodine contents of sulphide minerals it is sug- gested that in most cases at least 75% of the total iodine is strongly bound in these minerals.
