9529258 Lasaga This grant provides $154,875 as partial support of the costs of acquiring a new in-situ near- atomic resolution hydrothermal system and automated BET equipment for analysis of mineral surfaces in studies of dissolution and precipitation kinetics. The hydrothermal system will be custom built and used specifically for micro-scale analyses of dissolution and precipitation rates at crystal surfaces while the Brunauer-Emmett-Teller (BET) instrument will be purchased "off-the-shelf" and used for determination of reactive surface area of mineral powders. Determination of the reaction kinetics of silicate minerals is central to low temperature geochemical research and is essential to an understanding of environmental geochemical processes. ***

这笔拨款提供了154,875美元，作为购买新的原位近原子分辨率热液系统和自动化BET设备的部分费用，用于在溶解和沉淀动力学研究中分析矿物表面。热液系统将是定制的，专门用于晶体表面溶解和沉淀速率的微观分析，而布鲁诺尔-埃米特-泰勒（BET）仪器将是“现成的”购买的，用于测定矿物粉末的反应表面积。硅酸盐矿物反应动力学的测定是低温地球化学研究的核心，对理解环境地球化学过程至关重要。* * *
