Director General’s Message

The Geological Survey of Iran (GSI) was established in 1962, through a special fund project of United Nations. Although, the idea came to mind in January 1959, and the official permission was ratified by Iranian Senate and National parliaments in August 1959. After three years lasted for affiliated administrative affairs, GSI, under cooperation of Ministry of Industries and Mines, was officially founded in 1962.

Today, GSI is known for its long-term and extensive data-collection networks and research of Applied Geology, Geological Mapping, Mineral Exploration, Geohazards and Environmental Geology issues in the Region. These efforts provide policy makers, managers, scientists, and the general public with information needed to understand and make decisions about Iran’s natural resources.
