The Behavior of C-O-H-NaCl Fluids Determined from Synthetic Fluid Inclusions

本研究将研究400-750℃、0.5- 2.0 kb范围内H2O-CO2-CH4-NaCl体系中流体的行为。在开始对四元系统的研究之前，将优先研究三元子系统。实验将利用合成的流体包裹体在受控的温度和压力下捕获流体样本。最终目标是得出一种经验关系，从中可以预测特定P-T-X条件下流体的摩尔体积。这些结果最终将应用于许多碱金属和贵金属矿床的形成和演化、变质矿物组合的发育和变质过程中的热量传递、部分熔融作用等火成岩过程和成岩作用的研究。

9405629 Lamb This research will investigate the behavior of fluids in the system H2O-CO2-CH4-NaCl in the range 400-750 oC and 0.5- 2.0 kb. The ternary subsystems will have priority for study before research on the quaternary system is initiated. The experiments will utilize synthetically produced fluid inclusion to trap samples of fluids at controlled temperatures and pressures. The ultimate objective is to arrive at an empirical relationship from which the molar volume of a fluid can be predicted for specified P-T-X conditions. The results will ultimately find application in studies of the formation and evolution of many base and precious metal ore deposits, the development of metamorphic mineral assemblages and the transfer of heat during metamorphism, igneous processes such as partial metling, and diagenesis.
