More than 200 piercement salt plugs are present in southern Iran and in the Persian Gulf region. Recent investigations have shown the salt, the Hormuz Series, to be largely of Precambrian (late Proterozoic) age. The diapirs are famous for their tongue-like projections, known as "salt glaciers," and for their associated igneous, metamorphic, and sedimentary exotic blocks. In many places the salt plugs form spectacular mountains, rising up to 4,000 ft above the adjacent valley floor. The diapirs generally are associated with anticlines, and in many areas pierce the structure at the plunging end or on the flanks. Diapirs in synclines also are present.

The Geological Survey of Iran (GSI) was established in 1962, through a special fund project of United Nations. The GSI is authorized to carry out geological and mineral investigations throughout the country, to collect results of activities performed in this respect, to establish interrelationship and coordination between such activities and to prepare, complete, and publish geological maps of Iran. In 1999, the exploration duties of the Ministry of Mines and Metals were totally assigned to the GSI. The GSI is now responsible for the geological study of the country, and the exploration-evaluation of the mineral resources (except hydrocarbons).
