| Abstract: | The SHRIMP U-Pb ages for the zircons from the meta-intermediate-basic intrusive rocks cutting the Late Paleoproterozoic Jinshan Group in eastern Shandong Province,North China Craton are reported.The Jinshan Group is mainly composed of graphite-bearing meta-detrital sediment,meta-calc-silicate rock and marble with upper amphibolite-granulite facies metamorphism and is one portion of khondalite series widely distributed in the North China Craton.Meta-diorite with greenschist-facies metamorphism (S0835) has ma... |
