Abstract: Early Precambrian khondalite series, which mainly consist of Al-rich schists and gneissic rocks with thin layers of marble, are widespread in north Shandong Province, SE Sino-Korean craton. Four stages of the metamorphic history have been recognized in mineral assemblages based on petrographic features, genetic mineralogy, metamorphic reaction integrated with garnet, biotite and cordierite zonation patterns. The P-T conditions for each metamorphic stage were obtained using thermodynamically and experimentally calibrated geothermobarometers. Garent along with fine-grained inclusion minerals, defines a prograde assemblage (M1) garnet+biotite+plagioclase+quartz. The peak of metamorphism (M2) at about 760℃ and 10.0kb is defined by kyanite-bearing granulite-facies mineral assemblage. Symplectite or coronas of cordierite surrounding relict garnet indicate garnet occurring breakdown reaction at conditions around 750~800℃ and 4.0~5.4kb. Kelyphites of fine-grained biotite ±quartz around garnet formed during the cooling process (M4) at about 550~650℃ and ~4.0kb. These results define a sequential P-T path containing near-isothermal decompression (ITD) and near-isobaric cooling (IBC) stages. The clockwise hybrid ITD and IBC P-T paths of the Early Precambrian khondalite series in North Shandong Province imply a model of thickening followed by rapid uplifting in a collisional orogen.
