Особенности проявления рудных систем в геофизических полях в зоне влияния Чай-Юрьинского глубинного разлома (Центрально-Колымский регион)

The article presents the results of geological and geophysical studies performed within the Central Kolyma area, in the zone of the Chay-Yurya deep fault influence (Yana-Kolyma metallogenic system). A comprehensive approach to assessing the relationship of geophysical anomalies with the geological structure of the area is described. An apparatus for the statistical analysis of geophysical data was used. It has been established that the area of the Urya ore field is attached to the exocontact part and is characterized by the zonal structure. The exocontact zone is saturated with potentially ore-bearing dyke bodies, fixed by local low-amplitude positive anomalies of the magnetic field with an intensity of 2 to 30 NT. A set of deep geological and geophysical forecast criteria for gold mineralization is proposed in a hierarchical sequence: ore region - ore cluster - orefield - deposit.
