It was defined that as a result of saturation or migration of hydrocarbons, thin disperse magnetite, which can be revealed via thermal-magnetic research methods, has been formed. Moreover, the most sensitive parameters are I_rs/I_rso and I_rt/I_n associated with the temperature phase transformations of iron-containing compounds. The values of I_rs/I_rso and I_rt/I_n reach the dozens and hundred value units for the rocks saturated with oil, and the order of units for the rocks not underwent the contact with hydrocarbons.

Therefore, studying the values of I_rs/I_rso and I_rt/I_n, one can judge on the presence of iron compounds in the reservoirs and correspondingly, suppose whether this horizon served earlier as a reservoir, or medium for hydrocarbon migration.

Thermal-magnetic research surveys carried out by us justified that in the section of Productive Series in Azerbaijan the major magnetic minerals responsible for the primary magnetism of terrigene reservoirs of Upper Pliocene is the magnetite with
T_с = 550-575 ^oС and the hydrogethite with T_с = 100–120 ^oС. At the same time, abnormally high values of I_rs/I_rso and I_rt/I_n and I_rs/I_rso и I_rt/I_n parameters are observed as well. These data may justify that the age of Upper Pliocene in Productive Series of Azerbaijan is the most probable time for either formation of oil and gas deposits or for the migration of main hydrocarbon mass towards favorable structures (traps).
