Characterization of mantle-derived melts by trace element and water determinations in melt inclusions,glasses and whole rocks

水在火成岩的形成和行为中起着至关重要的作用。然而，尽管它很重要，但对熔体包裹体中水分含量的测定只有有限的几种。熔融包裹体存在于各种矿物类型中，形成了保存原始或最少脱气的水含量的极好容器。共聚焦拉曼光谱的最新发展表明，它是一种很好的定量水分含量的工具。这项研究的目的是利用拉曼光谱和其他原位分析技术来研究地幔岩浆随时间的起源。所获得的数据将有助于限制地球系统的演化和岩石圈-水圈的相互作用。

Water plays an essential role in the formation and behaviour of igneous rocks. However, in spite of its importance there are only a limited number of determinations of water contents in melt inclusions. Melt inclusions occur in a variety of mineral types and form an excellent vessel for the preservation of primary, or least degassed, water contents. Recent developments in confocal Raman spectroscopy show that it is an excellent tool for quantification of water contents. The aim of this study is to use Raman spectrometry and other in situ analytical techniques to study the origin of mantle-derived magmas through time. The data obtained will help constrain the evolution of the Earth System and lithosphere-hydrosphere interactions.
