%0 Journal Article %T Occurrence Mechanisms of Iodine-rich Surface Waters and Groundwaters and Their Relations with Oil and Gas Deposits %A Adil £¿zdemir %J - %D 2018 %X In this study, occurrence mechanisms of iodine-rich surface waters and groundwaters and the relationship between iodine-rich waters and petroleum systems were investigated. For this purpose, Western Caspian (Azerbaijan), Eastern Caspian (Turkmenistan), Sacramento (USA), Po (Italy) and Joban - Hamadori (Japan) petroliferous basins with published hydrogeochemical data of iodine-rich surface waters and groundwaters were selected. Iodine enrichment in the surface waters and groundwaters of these basins, which contain oil and gas deposits, are iodine-rich reservoir waters and hydrocarbons that migrate from the deep oil and gas deposits to the surface and near the surface with the effect of tectonic, volcanic and other geological events. Iodine in the surface waters and groundwaters of investigated petroliferous basins are the same origin as iodine in oilfield waters and derived from organic-rich rocks. Therefore, the geological and hydrogeochemical data of investigated basins prove the close relationship between iodine-rich surfaces and groundwaters (these waters are also rich by petroleum hydrocarbons) and petroleum systems. This close relationship shows that the potential of a basin with an unknown potential for oil and gas can be evaluated by iodine analysis on the cold and hot surface waters and groundwaters. This relationship is also important in terms of determining future exploration targets %K £¿yot %K iyot£¿a zengin sular %K yeralt£¿suyu kirlili£¿i %K petrol hidrojeolojisi %K petrol arama %U http://dergipark.org.tr/comufbed/issue/40663/440738
