Early Cretaceous arcrelated volcanic rocks in the northern

There are widespread Late Mesozoic volcanic rocks in the Great Xingan Range Northeast China. However the precise age data and tectonic evolution are still controversial. In this paper a suite of intermediatefelsic volcanic rocks and mafic volcanic rocks have been recognized in the Daheishan of the northern Great Xingan Range. Zircon UPb dating constrains two groups of the

Geochronology and geochemistry of Mesozoic dykes in the

Zircon UPb dating yielded the formation ages of these rocks as Triassic Jurassic and Early Cretaceous. LowMg adakitic granite porphyries formed at 233 Ma have zircon Hf t values of 17.7 to 14.5 suggesting that they were mainly derived from partial melting of thickened lower crust.
