Interactions Among Rocks, Solutions and Magmas in SubductionZones: Experimental Approach

[303967] Wyllie这个研究项目是关于挤压板块边界特征的侵入和挤压硅质岩浆的起源。物质、蒸汽和岩浆从俯冲的海洋地壳，通过上覆的地幔楔，进入大陆地壳的流动过程，将通过脱水熔融实验加以检验。特别感兴趣的项目包括10-20 kb范围内角闪岩和黑云母-角闪洞片麻岩的脱水熔融，10 kb玄武岩-方解石的相关系和熔融产物，以及确定水不饱和液体表面的二黄道长岩，作为解决地幔衍生的富含lil的太古宙二黄道长岩起源的一种方法。

9303967 Wyllie This research project is concerned with the origin of the intrusive and extrusive siliceous magmas characteristic of compressive plate boundaries. The processes involved in the flux of materials, vapors and magmas from subducted oceanic crust, through the overlying mantle wedge, and into the continental crust will be examined by means of dehydration- melting experiments. Projects of particular interest include the dehydration melting of amphibolite and biotite- amphibole gneisses in the 10-20 kb range, phase relationships and melting products from basalt-calcite at 10 kb, and determinination of the H2O-undersaturated liquidus surface of monzodiorite as a means to address the origin of mantle-derived LILE-enriched Archean monzodiorites.
