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

[405999 . Manning]该项目将继续进行实验研究，目的是提供评估高压流体-岩石相互作用的数据。拟进行的实验主要是测定顽辉石+橄榄石、透辉石+顽辉石、钠长石+石英和硬玉+石英在5-25 kb和400-900℃的水中的溶解度。另外的实验将研究天然板坯脱水流体的组成以及与榴辉岩平衡的流体组成。本文的研究成果将为揭示俯冲板块、地幔楔、巴罗威变质带等高压地质环境下的构造过程提供理论依据。

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.
