Fluids in the Deep Crust and Upper Mantle: Experimental Studies of Mineral Solubility at High Pressure

9405999曼宁该项目将继续实验研究，旨在提供数据，以评估高压流体-岩石相互作用。 本实验主要研究顽火辉石+镁橄榄石、透辉石+顽火辉石、钠长石+石英和硬玉+石英在5-25 kb、400- 900 oC条件下的溶解度。 另外的实验将调查天然板脱水流体和流体成分与榴辉岩平衡的组成。 这一研究成果将在解释高压地质环境中的过程中得到应用，如俯冲板片、地幔楔和巴罗变质带。

9405999 Manning The project will continue experimental studies aimed at providing data with which to evaluate high pressure fluid- rock interactions. The proposed experiments will focus on determining solubilities of enstatite + forsterite, diopside + enstatite, albite + quartz, and jadeite + quartz in H2O at 5-25 kb and 400-900oC. Additional experiments will investigate the compositions of natural slab dehydration fluids and fluid compositions in equilibrium with eclogite. Results of this research will find application in elucidating processes in in high pressure geologic environments such subducting slabs, the mantle wedge, and Barrovian metamorphic belts.
