AbstractThe evolutionary history of the NW Yangtze Block is important in interpreting its location and relationship with the Rodinia supercontinent. Although a Neoproterozoic arc-related tectonothermal event is recognized in the Micangshan area of the NW Yangtze Block, its timing and P-T conditions are poorly constrained. We address this issue by focusing on the garnet-biotite gneiss that represents the main lithology of the Huodiya Group on the NW margin of the Yangtze Block. This gneiss is predominantly composed of garnet, biotite, feldspar and quartz. The peak mineral assemblage in the matrix consists of garnet + biotite + quartz + plagioclase + K-feldspar. The retrograde stage is characterized by embayed rims of the garnet and its associated biotite in the matrix. The P-T conditions in the peak and retrograde stages are constrained to 7-8 kbar and c. 710 degrees C and 5-6 kbar and 650-675 degrees C, respectively, and suggest that 4-5 vol.% melt was produced during an upper amphibolitegranulite facies metamorphic event. The first report of monazite U-Pb dating in the Huodiya Group of the Micangshan area yielded aweighted mean Pb-206/U-238 age of 802 +/- 5 Ma. The studied samples contained detrital igneous zircons with Pb-206/U-238 dates >800 Ma, whereas the metamorphic zircons yielded a weighted mean Pb-206/U-238 age of 797 +/- 9 Ma. Based on the compressional tectonic environment and previous studies, we propose that the Yangtze Block was probably located on the periphery of the Rodinia supercontinent.
