摘要

The study of the geochemistry of the Late Cretaceous rhyolites of Daxingzhuang Formation in Yixian area, western Liaoning Province, was discussed. The geochemical features of the rhyolites indicate the magmas originated from the partial melting of eclogite of the lower thicken basaltic crust of the North China craton and perhaps also represent the thicken crust still existed in partial area of Yanshan orogenic belt. It falicitates the understanding of the processes of the lithosphere thinning of the North China craton during the Mesozoic and Cenozoic period.oft-com:office:office" />
