摘　　要：The GIS （geographic information system） used for predicting the associated with upper-intrusive zone of hydrothermal alteration IOCG （iron-oxide copper gold） mineralizing systems is shown by example of the northeast of Russian. IOCG ore deposits can have enormous geological resources with significant reserves of base, precious and strategic metals, are economically attractive targets for mineral exploration worldwide, but are still unknown in the northeast Russian. It was localized in Tarinskiy ore node （eastern Yakutia） field of brecciated altered rocks with sulfide and iron-oxide cement is a first in eastern Yakutia nature anomaly of IOCG-type with iron-oxide Cu-Au ± U specialization, that was formed close to the surface of Rep-Yuruinskiy pluton. It should be of interest as a new precious metals world class deposit type in northeast of Russia.

关 键 词：GIS iron oxide-Cu-Au ± U Rep-Yuruinskiy Tarinskiy ore node.
