A comparison of the Lushan granulite facies rocks and related amphibolite facies rocks with the granulite facies rocks in other parts of the world shows that the former rocks are not apparently depleted in LIL elements. The slight Rb and U depletion accompanied by no Th depletion suggests that granulite facies rocks have not been transformed by special fluids or melts,and that the slight Rb and U depletion might be attributed to the devolatilization that occurred during or bofore amphibolite facies metamorphism. The geochemical features, combined with the fact that there exist no CO2-rich fluid inclusions in the rocks and no positive Eu anomaly in the chondrite-normalized REE patterns of the rocks, have ruled out the possibility that the permeation of CO2 fluids and partial melting might have acted as the metamorphic mechanism of the granulite facies rocks. The trace element dlstribution patterns of the Lushan granulite facies rocks are equivalent to the patterns of the average crustal compositions on the southern margin of the North China platform, and this implies that there has been no obvious crust growth in this area since Proterozoic and that the material cycling1 has been mainly intracrustal recycling.The high heat-producing element contents of the Lushan granulite and amphibolite facies rocks might be one of the factors thathave caused the long heat nonequilibrium in the crust of the area and a series of tectonic activities since Proterozoic.
