Geochronology and Geochemistry of the Late Cretaceous to Paleocene Intrusions in East Gangdese, Lhasa, Tibet and Their Tectonic Significances

In this study,we determined the granite ages in the middle to east Gangdese batholith. Zircon ages from these granites are 57.6–68.7 Ma,indicating that intrusions were formed in the Late Cretaceous to early Paleocene. The large-ion lithophile elements are highly enriched,whereas some high-field-stre...2441-4668
