The contractual system of subsoil use in Iran is gradually transforming into the administrative one. 

Abstract: The research subject is mineral resources management in the Republic of Iran in the 19th – the 21st centuries. The authors give special attention to the formation of the national legislation of Iran on natural resources. The authors consider three stages of the modern legal regime of mineral resources management in Iran: the first – contractual – stage, the second – national – stage, and the third – normative legal (post-revolutionary) – stage. Special attention is given to the legal regime of Iran’s continental shelf and to the contracts of the National Iranian Oil Company with agents, contractors and foreign investors. The research contains the information about the formation and development of the system and the structure of governmental management of mineral resources in Iran. The research methodology is based on general scientific methods (dialectics, comparison, analysis, synthesis, analogy, induction, deduction, etc.) and specific methods (formal-legal, comparative-legal, historical-legal, the method of governmental regulation, the system method, the method of prognostication, etc.). The scientific novelty of the article consists in the fact that it reveals the historical patterns of formation and development of Iran’s legislation on natural resources; defines the stages of its formation including the legislation on the continental shelf; studies the essential terms of contracts and patents on joint mineral resources management; defines the legal status of the participants of mineral resources production including foreign investors; describes the historical dynamics of the system and the structure of state management of mineral resources in Iran; and reveals the tendencies of the further development of Iranian legislation on mineral resources management.
