In order to investigate the mechanism of fluid expulsion from polycrystalline aggregates, we carried out sintering experiments of quartzite with variable XCO2 (CO2/H2O+CO2). When XCO2=0, fluids were expelled through interconnected networks to the upper part of the experimental capsules within 192 h. When XCO2=0.39-0.79, fluids were retained among the quartzite grains by forming intergranular fluid pockets. These pockets were formed by rearrangement and coagulation of fluid filled pores.
