Petrographic features,isotopes,and trace elements were determined,and fluid inclusions were analyzed on frac-ture -filling,karst-filling and interparticle calcite cement from the Ordovician carbonates in Tahe oilfield,Tarim basin,NW *** aim was to assess the origin and evolution of palaeo-waters in the *** initial water was seawater diluted by meteoric water,as indicated by bright cathodoluminescence(CL) in low-tempera-ture *** palaeoseawater was further buried to temperatures from 57 to 110℃,nonluminescent calcite precipitated during the Silurian to middle *** of meteoric water of late Devonian age into the carbonate rocks was recorded in the first generation of fracture- and karst-filling dull red CL calcite with temperatures fromhydrothermal water may have entered the carbonate rocks,from which precipitated a second generation of fracture-filling and interparticle calcite and barite cements with salinities greater than 22.4 wt%,and temperatures from 120°C to 180°*** hydrothermal water may have collected isotopically light CO(possibly of TSR-origin) during upward migration,resulting in hydrothermal calcite and the present-day oilfield water havingδC values from -4.3 to -13.8‰and showing negative relationships of Sr/Sr ratios toδC andδO ***,higher temperatures(up to 187℃) and much lower salinities (down to 0.5 wt%) measured from some karst-filling,giant,nonluminescent calcite crystals may suggest that hydrothermal water was deeply recycled,reduced(Fe-bearing) meteoric water heated in deeper strata,or water generated from TSR during hydrothermal water *** of hydrothermal and local basinal water(or diagenetically altered connate water) with meteoric waters of late Permian age and/or later may have resulted in large variations in salinity of the present oilfield waters with
