首席研究员将研究同成因硅欠饱和和硅饱和火成岩的起源和历史。具体地说,他将通过加入富含二氧化硅的地壳成分来解决后者是否与前者有关的问题。来自四个特定地点的岩石将使用岩石学,主要和微量元素分析,地质年代学和稳定同位素技术进行调查。要研究的过程可能是常见的。因此,研究结果将在帮助地质学家了解深成火成岩的起源方面具有潜在的广泛适用性。
英文摘要
The principal investigator will study the origin and history of cogenetic silica undersaturated and silica saturated igneous rocks. Specifically, he will address the question of whether the latter can be related to the former via incorporation of silica- rich crustal components. Rocks from four specific localities will be investigated using petrographic, major and trace element analytical, geochronologic, and stable isotope techniques. The processes to be studied are likely to be common ones. The research results thus will have potentially wide applicability in helping geologists understand the origins of plutonic igneous rocks.
