含铁

The zircon was dated by using the technique of single-zircon stepwise evaporation-deposition with a thermal ion mass spectrometry (Bernd Kober, 1986 and 1987). The zircon ages are 2.60-2.54 Ga for biotite-leptynite, 3.36-2.62 for mimatized leptite, and 3.53-3.08 Ga for quartzite from the iron formation.
