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.

部分熔化。颗粒状的相变质和大陆地壳的演变。大陆的地下室主要由古老山带深层融化的岩石组成。这种颗粒状的相岩石是理解大陆进化的关键。现在，使用熔体热力学的模型，可以首次定量研究部分熔化过程。将基于岩石的颗粒相的研究与热力学计算相结合，将允许颗粒相岩石岩石，因此，大陆壳的演变可以更好地理解。
