Iodargyrite is simple silver iodide; the mineral names comes the composition, using the Greek root argyros for silver. Iodargyrite has hexagonal symmetry and the wurtzite crystal structure. At Broken Hill, large concentrations of this mineral provided a rich silver ore. French chemist Vauquelin (1825) first noted the presence of iodine in silver ores, but it waited until Leymerie (1859) to name this mineral species.
Iodargyrite here forms a crystalline mass, 20 by 8 mm, showing hints of hexagonal forms on its edges. On a dense gossan and iron-stained quartz matrix. Some small associated microcrystals appear to be miersite.
