9405362 Dove This research will elucidate the rates and mechanisms by which aluminum interacts with silica surfaces. Specifically it will quantify the kinetics of quartz dissolution in characterized aluminum-bearing solutions and relate this kinetic information to in situ observations of reaction processes occurring at the mineral surface in aqueous solutions. This work is possible due to the development of techniques that directly measure mineral-solution reaction rates to 300oC (MFR) and techniques that directly observe reaction processes occurring at the mineral surface in aqueous solutions (SFM). Results of the study will find application in botn mineral-water geochemical systems in both low temperature and hydrothermal environments.

9405362 Dove这项研究将阐明铝与硅表面相互作用的速率和机制。具体来说，它将量化石英在特征含铝溶液中的溶解动力学，并将这些动力学信息与在水溶液中矿物表面发生的反应过程的现场观察联系起来。由于直接测量矿物-溶液反应速率至300℃（MFR）的技术和直接观察水溶液中矿物表面发生的反应过程（SFM）的技术的发展，这项工作成为可能。研究结果将在低温和热液环境下的地下水地球化学系统中得到应用。
