摘要：
Three stages in formation of the Svetlinsk gold-telluride mesothermal deposit were established. Gold precipitated as native gold or gold tellurides. Different age-relationships are suggested for the timing of precipitation of metallic gold and gold-bearing tellurides. Fluid inclusion studies indicate that the mineralising fluid was a mixture of H2O + CO2 + N-2 + CH4 + NaCl. Its salinity ranges of 4.8 to 18 wt0/o NaCl-equiv. The calculated isotopic composition of the fluids is typical of fluids exsolved from a granite magma.
