Zircons formed at 3.08; 3.17-3.19 and 3.23 Ga were found in metaterrigeneous rocks that occur between horizons of iron-bearing quartzites on the Chertomlyk volcanogenic iron ore deposit. The youngest detrital zircon crystallized at 3.08 Ga signifies the maximal age of sedimentation. The 3.17-3.19 Ga...
