Partial melting. granulite facies metamorphism and the evolution of the continental crust. The basement of the continents is made up largely of rocks that have partially melted at deep levels in ancient mountain belts. Such granulite facies rocks hold a key to understanding the evolution of the continents. Now, with a model for the thermodynamics of melt, partial melting processes can be investigated quantitatively for the first time. Integrating rock-based studies of granulite facies terrains with thermodynamic calculations will allow granulite facies rocks, and, as a consequence, the evolution of the continental crust, to be much better understood.

部分融化。麻粒岩相变质作用与大陆地壳演化。大陆的基底主要是由古代山带深处部分融化的岩石组成的。这种麻粒岩相岩是了解大陆演化的关键。现在，有了熔体热力学模型，可以第一次定量地研究部分熔化过程。将麻粒岩相地形的基于岩石的研究与热力学计算相结合，将使麻粒岩相岩石以及大陆地壳的演化得到更好的理解。
