The Cheleken Peninsula, located on the eastern coast of the Caspian Sea, according to experts, contains huge resources of hydrocarbon raw materials. The first information on oil produced there dates back to 1876. The current area of the peninsula, stretching from the west to the east, is about five hundred square kilometers. The peninsula is geologically located in the Caspian Depression and is composed of Mesozoic and Quaternary sedimentary rocks. As a result of tectonic movements, it has repeatedly been subject to shifts and vertical cracks and formed fault lines with no specific direction. It is this situation that caused the eruptions of deep volcanoes from deep layers of the earth and the accumulation of iodine-bromine waters.
The word “Cheleken”, derived from the words “çar” and “kan”, means “four abundances” or “four riches” (oil, lubricants, salt and dyes). The production of iodine, bromine and mercury was successfully carried out for decades in the modern city of Hazar, which in ancient times was called Akjayar.
