This award will provide funds for Prof. Michael F. Sheridan of Arizona State University to travel to Italy to conduct field work and collaborative research at three different Quartenary volcanos in Italy with his Italian counterparts, Prof. L. La Volpe (Bari), L. Civetta (Naples), and G. Cavaretta (Rome). The general objective of the proposed research is to achieve a better understanding of the physics of volcanic activity through geochemical investigations at the proposed sites. The specific objectives are: 1) to reconstruct the volcanic history of Vulcano in Sicily, following a field investigation of the oldest exposed stratigraphic sequence; 2) to interpret explosive volcanic phenomena recorded in the products of eruptive cycles younger than 50,000 years on Pantelleria (Straight of Sicily), using the variation in volatile species and light trace elements measured by the ion microprobe; and 3) to investigate the geochemistry of boron and other light elements in the hydrothermal minerals of the Sabatini Volcanic District (Latium). The activity planned at Vulcano is important for its likely contributions to the basic science of volcanology vis a vis volcanic hazards. The work at Pantelleria is of potential scientific value since it promises, through the application of ion microprobe analysis, to yield important analytical data on the volatile and light element content of glass inclusions and phenocrysts, thus providing information on the volatile concentrations of the magmatic reservoirs of the volcano. The proposed research project will take advantage of the combined skills and expertise of the U.S. and Italian investigators, who have worked together effectively as a team in the past, in the conduct of preliminary field work at the volcanic sites and the completion of laboratory analysis in Naples and Arizona State University.

该奖项将资助亚利桑那州立大学的Michael F.Sheridan教授前往意大利，与他的意大利同行L.La Volpe教授(Bari)、L.Civetta教授(那不勒斯)和G.Cavaretta教授(罗马)一起在意大利的三个不同的第四纪火山开展实地工作和合作研究。拟议研究的总体目标是通过对拟议地点进行地球化学调查，更好地了解火山活动的物理机制。具体目标是：1)在对最古老的暴露地层层序进行野外调查后，重建西西里岛Vulcano的火山史；2)利用离子探针测量的挥发性物种和轻微量元素的变化，解释Pantelleria(西西里岛的笔直)5万年前喷发旋回记录的爆炸性火山现象；3)研究萨巴蒂尼火山区(Latium)热液矿物中硼等轻元素的地球化学特征。计划在Vulcano进行的活动很重要，因为它可能对与火山灾害有关的火山学基础科学做出贡献。Pantelleria的工作具有潜在的科学价值，因为它承诺通过应用离子微探针分析，提供关于玻璃包裹体和斑晶的挥发性和轻元素含量的重要分析数据，从而提供关于火山岩浆储集层的挥发性浓度的信息。拟议中的研究项目将利用美国和意大利调查人员的综合技能和专业知识，他们过去曾作为一个团队有效地合作，在那不勒斯和亚利桑那州立大学进行初步实地工作，并完成实验室分析。
