英文摘要	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 magmatic zircons with a Pb-207/Pb-206 weighted mean age of 1852 +/- 9Ma (MSWD = 2.1), Meta-gabbro (S0816) has mineral association of amphibolite facies metamorphism, but zircons from this rock show fir-texture which is considered to be a feature of zircons formed under granulite facies metamorphism. The metamorphic zircons have a Pb-207/Pb-206 weighted mean age of 1865 +/- 11Ma (MSWD = 0.76). Combined with regional data obtained earlier, some conclusions can be drawn as follows (1) new zircon elating further supports that the Jingshan Group was formed during the Late Paleoproterozoic; (2) in the eastern Shandong Province, the time from compression to extension was before 1.87Ga during the Paleoproterozoic. This is similar to the Daqingshan and Hengshan areas, western North China Craton, where the extension is considered to start at 1.95 similar to 1.92Ga in terms of zircon dating of meta-basic dykes and ultra-high temperature metamorphic rocks.
