9316721 Altaner This award will support collaborative research between Stephen Altaner, University of Illinois, and Antonio Pozzuoli of the University of Naples, Italy. The proposed research has two general objectives: 1) Improved understanding of the mechanism of the smectite to illite reaction through study of a suite of illite- and smectite-bearing samples from Ponza island, Italy, and 2) assessment of the nature of hydrothermal alteration of the Green Tuff and overlying breccia of Ischia (Italy), designed to lead to improved evaluation of volcanic risk on Ischia. Professor Pozzuoli is a specialist in the mineralogy and petrology of clay minerals, particularly those of the Ponza bentonite. He and his colleagues are also experts in the geology of Ponza and Ischia, critical to the collection of appropriate samples. Professor Altaner and his colleagues bring to the collaboration expertise and facilities for integrated state-of- the-art analyses of geologic samples, including K/Ar dating, NMR, oxygen isotope geochemistry, XRD, and TEM analyses. ***

9316721阿尔塔纳该奖项将支持伊利诺伊大学的斯蒂芬·阿尔塔纳和意大利那不勒斯大学的安东尼奥·波佐利之间的合作研究。拟议的研究有两个总体目标：1)通过研究意大利庞萨岛的一套含伊利石和蒙皂石的样品，提高对蒙皂石到伊利石反应机理的理解；2)评估(意大利)伊斯基亚的绿色凝灰岩和上覆角砾岩的热液蚀变性质，旨在改进对伊斯基亚火山风险的评估。Pozzuoli教授是粘土矿物矿物学和岩石学方面的专家，尤其是庞萨膨润土的矿物学和岩石学专家。他和他的同事也是庞萨和伊斯基亚地质方面的专家，这对收集适当的样本至关重要。Altaner教授和他的同事为合作带来了集成最先进的地质样品分析的专业知识和设备，包括K/Ar测年、核磁共振、氧同位素地球化学、X射线衍射和透射电子显微镜分析。***
