Iron oxide and rare earth precious metal deposits of the Jewish Autonomous Region as a new type of the IOCG deposits

The purpose of the work is to consider complex ores (Fe, Au, Pt, Ag, REE) in the Proterozoic iron deposits in the JAR and compare them with the largest deposits of the IOCG type. The reserves and resources in the Jewish Autonomous region iron ore deposits, with an iron content of 35%, are equal to 3 billion tons. As for the related metals in the iron ores, the iron deposits in the region are similar to the Proterozoic copper-uranium giant Olympic Dam, with an iron content of 35%. The complex of valuable metals in it is superimposed on earlier iron ores. The second model type of Proterozoic IOCG deposits is a giant Bayan Obo rare earth metal deposit in China. In the ores of the iron deposits of the JewishAutonomous Region, gold and platinum amount to 0.5–1 g/t. The iron ore deposits in the Jewish Autonomous region, with significant concentrations of precious metals, represent the IOCG deposits new third type.
