Mineralpedia Details for Iodargyrite
Iodargyrite
Named for the composition of iodine (iod) and silver, after the Greek word argyros (argyr). Somewhat uncommon, Idoargyrite can be found in abundance or of good quality in localities in Mexico, the United States, Chile, Australia, Germany, Spain, France, and Kazakhstan. Iodargyrite forms as a secondary mineral in oxidized silver-bearing deposits.
