这是先前由NSF支持的研究的延续 授权号85-19237，涉及实验测定 矿物在高温高压下的溶解度。 它 通常认为，水性流体在 地球岩石圈的许多地质过程;然而， 矿物溶解度和流体-岩石平衡的基本数据 在高温和高压下是非常稀少的。 这 项目将确定地质平衡溶解度 H2O-CO2中重要的氢氧化物、碳酸盐和硅酸盐矿物 流体温度可达750 oC，压力可达3 kbar。 的 这些实验的结果将提供更好的理解 涉及流体-岩石相互作用的重要变质过程。

This is a continuation of research previously supported by NSF grant EAR 85-19237, involving the experimental determination of mineral solubilities at elevated temperatures and pressures. It is generally accepted that aqueous fluids play a critical role in many geological processes in the Earth's lithosphere; however, fundamental data on mineral solubilities and fluid-rock equilibria at elevated temperatures and pressures are extremely sparse. This project will determine equilibrium solubilities of geologically important hydroxide, carbonate, and silicate minerals in H2O-CO2 fluids at temperatures to 750oC and pressures to 3 kbar. The results of these experiments will provide better understanding of important metamorphic processes involving fluid-rock interactions.
