Zircon U-Pb ages and geochemistry of Early Cretaceous volcanic rocks, northwestern Korean Peninsula: Constraints on Late Early Cretaceous continental arc distribution in Northeast Asia

In the northwestern Korean Peninsula, Cretaceous volcanic rocks are composed of andesite, andesite-dacite and rhyolite intercalated with terrigenous clastic rocks. Zircon grains selected from these rocks are authigenic zircons with obvious crystal edges and oscillatory zoning, their Th/U ratios bein...
