Phase Equilibria and Speciation of Water and Carbon Dioxide in Silicate Melts

这项提议是为了继续资助对水和二氧化碳--陆地火成岩中最丰富的挥发性成分--的模型和自然火成岩系统中行为的研究。这些组分的加入对硅酸盐熔体的行为有重大影响，了解这些影响对于了解岩浆起源和演化至关重要。总体目标是通过对实验室在受控条件下合成的样品的仔细研究，对这些挥发性成分的行为有一个基本的了解，并利用合成样品的研究结果和技术来解决与火成岩的岩石成因有关的具体问题。

This proposal is for continued funding to support research into the behavior in model and natural igneous systems of water and carbon dioxide -- the most abundant volatile components in terrestrial igneous rocks. Addition of these components has significant effects on the behavior of silicate melts and knowledge of these effects is critical to understanding magma origin and evolution. The overall goals are to develop a fundamental understanding of the behavior of these volatile components through careful investigation of samples synthesized in the laboratory under controlled conditions and to use the results and techniques developed from study of the synthetic samples to solve specific problems related to the petrogenesis of igneous rocks.
