Neoproterozoic zircon inheritance in eastern North China craton(China) Mesozoic igneous rocks:derivation from the Yangtze craton and tectonic implications CAJ下载PDF下载
<正>We propose that inherited Neoproterozoic zircons in Mesozoic igneous rocks from the eastern portion of the North China craton(NCC) were initially derived from the Yangtze/South China block,rather than from the NCC itself.The mechanism that introduced these zircons into the NCC was likely tectonic underplating during Triassic continental subduction/collision of the Yangtze block beneath the NCC.The addition of abundant crustal materials represented by the exotic zircons,probably along the Moho or weak int...
