Abstract

Iran has been divided into several structural units, each characterized by a relatively unique record of stratigraphy, magmatic activities, metamorphism, orogenic events, tectonics, and overall geological style. It is imagined that Precambrian Rocks has extent in Iran and some of them are characterized more than 1.5 billion years. However it is characterized that many rocks are pertaining to Precambrian but it has an age young than 900 million years. Some of these complexes and some of formations are pertaining to Precambrian and Infracambrian in old reports and they are: kahar Formation, Tashk, Morad series, Rhizo Series and Dezu in central Iran. Stratigraphy and fossil studies in last years, results from changes in stratigraphy position in some of mentioned rocks. These deposits constitute the most largest and important economical deposits of Iran. The Chador Malou, Choghart, Golgohar, Sechahoun and Gelmandeh Iron Ore deposits, Kushk lead sphalerite mines, Saghand and Narygan Uranium deposits and Esfordy phosphate, deposits are the some of these examples. Based on new investigation it is suggested that the separation of ore rich melt and the ensuing hydrothermal processes dominated by alkali metasomatism were both involved to different degrees in the formation of ore deposits in Central Iran. Because of high concentration of various and largest deposits in this limited area of Precambrian age we can call the Precambrian of Central Iran as metallogenic province and metallogenic epoch.
