首席研究员将进行旨在 评估近平衡矿物流体反应动力学在升高 温度和压力。这些实验最近将联合收割机 开发了同位素掺杂技术与流通方法 为了更好地限制流体化学和温度对 矿物溶解和沉淀的速率, 反应的亲和力接近于零。结果将应用于 热液蚀变过程和海底地热系统。
英文摘要
The principal investigator will conduct experiments designed to assess near-equilibrium mineral-fluid reaction kinetics at elevated temperatures and pressures. The experiments will combine recently developed isotopic doping techniques with flow-thru approaches to better constrain the role of fluid chemistry and temperature on the rate of mineral dissolution and precipitation when chemical affinity of the reaction is near-zero. Results will be applied to hydrothermal alteration processes and submarine geothermal systems.
