Abstract

Abstract

The Luoguhe molybdenum granite in Daxinganling region, with zircon U-Pb age of 131±2 Ma, belongs to monzogranite, included in high-K calc-alkaline series, with low ΣREE, obviously negative Eu anomaly, low Sr and high Yb. The granite is formed in Early Cretaceous post-collision. The 40Ar-39Ar age of muscovite in greisen is 125.36 ±0.90 Ma. Analysis shows that, around 130 Ma, the Daxinganling region experienced an important tectonic magmatismmineralization period.
