Natural resources

There are natural resources such as oil, lime, sand and salt in the peninsula. The peninsula has famous lakes like Masazir, Khojahasan and Boyuk Shor. Several ancient oil wells of the world are located in the Absheron Peninsula. Azerbaijan is in the first place for the variety of mud volcanoes in Absheron. 400 out of 800 mud volcanoes in the Asia (1100 in the world) are located within the Southern Caspian oil-gas basin as well as in the dry areas of Azerbaaijan and other islands in the water area of the Caspian Sea.

Main roads

The main highways of the country are in Baku and the Absheron Peninsula. These are the highways of Heydar Aliyev International Airport, Sea port, Baku Railway Station and others which connect the capital to other regions of the country. Major oil and gas pipelines go through here. Baku TRACECA (Transport Corridor Europe–the Caucasus–Asia) is the major point of the international traffic corridor. Within this project, Azerbaijan participates in the re-establishment of the historic Silk Road.
