KastnerAbstractThe PI will measure of Cl concentrations and isotope systematics in subduction-related aqueous fluids and rocks. The main objectives are to determine Cl concentrations and isotope compositions in: 1) pore fluids and sediments from the Costa Rica subduction zone; and 2) serpentine samples from subduction zones and transform faults. The work would result in an improved understanding of the cycling of volatiles (Cl, H2O) during tectonic processes and is of broad scientific interest.

KastnerAbstractPI 将测量与俯冲相关的水性流体和岩石中的 Cl 浓度和同位素系统学。主要目标是确定以下物质中的 Cl 浓度和同位素组成： 1) 哥斯达黎加俯冲带的孔隙流体和沉积物； 2）来自俯冲带和转换断层的蛇纹岩样本。这项工作将有助于更好地了解构造过程中挥发物（Cl、H2O）的循环，并且具有广泛的科学意义。
