Dynamics of fluid boiling in hydrothermal system and formation of mineral deposits

通过实验测定重金属的汽液分配系数，以了解重金属在蒸汽中的迁移和沉淀形成矿床的过程。挥发性金属如铜在还原硫物质存在下选择性地分配到蒸气中。矿石和脉石矿物的氧、氢、硫同位素组成阐明了成矿流体的来源。斑岩型金矿是由岩浆成因的成矿流体形成的，变质水是造山型金矿形成的重要条件。岩浆水和大气沃茨都是低温热液矿床的成因。

Vapor/liquid partitioning coefficients for heavy metals were experimentally determined in order to understand the process of metal transport in vapor and precipitation to form mineral deposits. Volatile metals such as copper selectively partitioned into vapor under the presence of reduced sulfur species. Oxygen, hydrogen and sulfur isotopic compositions for ore and gangue minerals clarify origin of ore-forming fluids. Porphyry type deposits are formed from ore-forming fluid of magmatic origin, and metamorphic water is important for the formation of orogenic-type gold deposits. Both magmatic and meteoric waters are responsible for epithermal deposits.
