Experimental Constraints on Volatile Cycling in Subduction Zones

这项研究将提供关于安山岩成分熔体中CO2和H2O溶解度的数据，以及俯冲板块中三种主要岩石类型（变质沉积岩、变质玄武岩和水合橄榄岩）中含水矿物稳定性的数据。即将进行的实验将使用高压系统的组合，覆盖范围为20 Mpa至20 Gpa。溶解度实验的温度范围为1100℃~ 1450℃。含水矿物稳定性实验将覆盖适合俯冲板块材料的范围，一般为5500 ~ 1200℃。在可能的情况下，实验结果将在现有理论模型的背景下进行分析，并将结果应用于解释俯冲带过程。

9506494 Holloway This research will provide data on the solubility of CO2 and H2O in andesitic composition melts and on the stability of hydrous minerals in the three prominent rock types in subducting slabs - metasediments, metabasalts, and hydrated peridotites. The experiments to be conducted will use a combination of high pressure systems covering the range 20 Mpa to 20 Gpa. The solubility experiments span the temperature range 1100o to 1450o. The hydrous mineral stability experiments will cover the range believed appropriate for subduction slab materials, generally 550o to 1200oC. Where possible, experimental results will be analyzed in context of available theoretical models and the results applied to interpretation of subduction zone processes.
