英文摘要Donghai rocked quartz deposit is located in the Su-Lu Ultra-high pressure (UHP) metamorphic zone, Jiangsu province. Its genesis and its relationship with UHP metamorphism remain unclear. Petrographic, microthermometric, and the Laser Raman investigations recognized that there are three types fluid inclusions in rocked quartz, i.e. pure liquid H2O2 liquid-vapor H2O and CO2-H2O fluid inclusions, the liquid-vapor H2O fluid inclusions are dominated, it size are range from 5 to 50 mu m, but that of liquid-vapor H2O fluid inclusions in rutile-bearing rocked quartz are more than 300 mu m. In additional to H2O and CO2, there are minor N-2, CH4, H2S and C2H, also are detected in the fluid inclusions. In different decrepitation temperature, the fluid inclusions release different gases, for example, in low temperature, H2O and CO2 were released with minor H2S, CH4 and C2H6, whereas in high temperature, H2O, CH4, C2H6, and CO2 were released with minor N-2 and H2S. The homogenization temperature and salinity of fluid inclusions in rocked quartz are divided into three sections respectively, i.e. 100 degrees C similar to 120 degrees C 160 degrees C similar to 220 degrees C and 240 degrees C similar to 260 degrees C and 0 similar to 2 wt% NaCl, 4 similar to 12wt% NaCl, 14 similar to 16wt% NaCl, which reflect multi-stage fluids overprinted in rocked quartz. The delta O-18 and delta Si-34 in quartz range from -5.6 similar to + 4. 6 parts per thousand and -0.2 similar to + 0.2 parts per thousand, respectively, but those in rutile-bearing quartz, are in the range from 10. 5 similar to 14.9 and -0.2 similar to + 0.1 parts per thousand, respectively. Contrasted with chlinochlore related to rocked quartz, the scale-biotite is more rich in Nb,Cr,Fe,V,W,Ti and Zr. This paper indicates that rocked quartz deposit in Donghai is related to quartz-bearing eclogite overprinted by different fluids after the exhumation, the rutile-bearing quartz is overprinted by fluids rich in Nb and Ta.
