Abstract Saline fluids are common to a variety of geologic settings in Earth's crust and upper mantle. The binary system H2O-NaCl is commonly used to interpret data obtained from fluid inclusions, and for geochemical modeling of mass and energy transport and fluid-rock interaction. Modeling of fluid properties in this binary system has generally relied on piecemeal compilations from available models specific to certain properties, whereas a standalone, comprehensive tool has been lacking. Here, we present a new computer package, entitled ProBrine (Properties of Brine) to evaluate the thermodynamic and transport properties of H2O-NaCl fluids over the range of temperatures from 0 to 1000 °C, pressure from 1 to 5000 bar, and salinity from 0 to 100 wt% NaCl. ProBrine is designed to calculate a wide range of thermodynamic and transport properties, including (but not limited to): phase equilibria (liquid, vapor, and halite); molar volume, density, specific enthalpy, and viscosity. The program is also equipped to calculate derived properties such as: 1) the coefficient of isobaric thermal expansion; 2) the coefficient of isothermal compressibility; 3) the reduced susceptibility; 4) the isobaric specific heat capacity, and the fluxibility. In addition, the model will calculate solubility of the following six minerals: fluorapatite, calcite, corundum, fluorite, rutile, and quartz, as well as the respective temperature and pressure derivatives, which can be used to predict mineral dissolution and precipitation along a flow path. Moreover, the program is equipped to interpret fluid-inclusion data. The program is written in Visual Basic (VBA) in Microsoft Excel and is released open-source, allowing a user full scope to review, copy, modify and expand the program code.

H2O-NaCl 流体热力学和传输特性的综合数值模型

摘要 地壳和上地幔的各种地质​​环境中都含有盐分流体。二元系统 H2O-NaCl 通常用于解释从流体包裹体中获得的数据，以及用于质量和能量传输以及流体-岩石相互作用的地球化学建模。在这个二元系统中对流体特性进行建模通常依赖于特定于某些特性的可用模型的零碎编译，而一直缺乏独立的综合工具。在这里，我们展示了一个名为 ProBrine（盐水的特性）的新计算机包，用于评估 H2O-NaCl 流体在 0 到 1000 °C 的温度范围内、1 到 5000 bar 的压力和从0 至 100 重量％氯化钠。ProBrine 旨在计算各种热力学和传输特性，包括（但不限于）：相平衡（液体、蒸气和岩盐）；摩尔体积、密度、比焓和粘度。该程序还配备计算衍生属性，例如：1）等压热膨胀系数；2）等温压缩系数；3) 降低的敏感性；4) 等压比热容和流动性。此外，该模型还将计算以下六种矿物的溶解度：氟磷灰石、方解石、刚玉、萤石、金红石和石英，以及各自的温度和压力导数，可用于预测矿物沿流动的溶解和沉淀小路。此外，该程序还可以解释流体包含数据。该程序是用 Microsoft Excel 中的 Visual Basic (VBA) 编写的，并开源发布，
