摘　　要：The characters of fluid compositions and fluid-rock equilibrium system of the Archean Fuping gneiss complex, Taihang Mountains are first determined by fluid-rock equilibrium thermodynamics calculations and mi-crothermometry of fluid inclusions. These investigations suggest that the X(H2O) is generally less than 0.05 in fluids equilibrating with the granulite facies metamorphic mineral assemblage of Fuping gneiss complex, and fluid-rock interaction is chiefly controlled by CO2-rich fluid infiltration.The characters of fluid compositions and fluid-rock equilibrium system of the Archean Fuping gneiss complex, Taihang Mountains are first determined by fluid-rock equilibrium thermodynamics calculations and mi-crothermometry of fluid inclusions.
