摘要：

The evolution of mineral-forming solutions in copper-molybdenum deposits of Kuznetsk Alatau, Eastern Transbaikalia, and Middle Asia is considered on the basis of the study of gas-liquid inclusions in minerals of different stages and mineral assemblages. The data permit estimation of the temperature, the state of aggregation, the composition, and the pressure of the solutions at various stages. The principal ore deposition occurred from liquid solutions enriched in carbon dioxide at 400 degree to 200 degree C. Solutions from deposits of Kuznetsk Alatau are essentially fluoride during the early stages and fluoride-carbonate rich at later stages. Those of Eastern Transbaikalia deposits are rich in chloride at early stages, chloride and carbonate at later stages. Those of Middle Asia deposits are rich in chloride.
