U.S.-Russian Cooperative Research on SO2 and Trace Metal Fluxes from Kudriavy Volcano, Kurile Islands (Russia)

9505523威廉姆斯 这个美国-俄罗斯合作研究赠款用于“千岛群岛（俄罗斯）库德里亚维火山的二氧化硫和微量金属通量”，由亚利桑那州立大学的斯坦利威廉姆斯博士和来自实验矿物学研究所（莫斯科）、火山地质学和地球化学研究所（堪察加彼得罗巴夫拉斯克）以及火山学和地球动力学研究所（尤日诺-萨哈林斯克）的俄罗斯科学家合作研究。 Kudriavy火山是研究岩浆金属通量的理想场所，因为它具有极高的温度（高达940 C），强烈的气体通量，常见的钙碱性安山岩成分，以及缺乏与岩浆气体相互作用以改变其成分的热液系统。 研究这些纯岩浆高温条件下的金属通量将有助于进一步限制钙碱性岩浆体中金属脱气的质量。 该研究将：（1）利用COSPEC测量SO_2通量，确定稀有金属通量，（2）直接对高岩浆弧型火山气体进行氧、氢、硫、碳、氮、氦同位素组成的测定，并研究温度对同位素组成的影响，（3）利用所获数据推断稀有金属的最终来源，（4）利用COSPEC测量的SO_2通量，确定稀有金属通量，（5）利用COSPEC直接对高岩浆弧型火山气体进行氧、氢、硫、碳、氮、氦同位素组成的测定，并研究温度对同位素组成的影响。（4）测量千岛弧附近其他火山的SO2通量：Baranski，Ivan Grozniy和Burevestnik。 这一拟议中的地质科学研究通过使美国和俄罗斯的领先专家能够联合收割机互补人才并在相互感兴趣和有能力的领域汇集研究资源来实现推进科学的计划目标。 讲习班还将用于提高研究生和本科生对粒子物理学的兴趣。 ***

9505523 Williams This U.S.-Russian Cooperative Research grant is for "SO2 and Trace Metal Fluxes from Kudriavy Volcano, Kurile Islands (Russia)" is between Dr. Stanley Williams of Arizona State University and Russian scientists from: the Institute of Experimental Mineralogy (Moscow), the Institute of Volcanic Geology and Geochemistry (Petropavlask-Kamchatsky), and the Institute of Volcanology and Geodynamics (Yuzhno-Sakhalinsk). Kudriavy volcano is a perfect location of studying metal fluxes from magmas due to its extremely high fumarole temperature (up to 940 C), strong gas flux, common calc-alkaline andesitic composition, and the lack of a hydrothermal system which would interact with the magmatic gases to change their composition. Studying metal fluxes at these purely magmatic high temperature conditions will help further to constrain the mass of metals degassing from calc-alkaline magma bodies, in general. The research will: (1) measure SO2 flux by COSPEC and determine rare metal fluxes; (2) direct fumarole gas sampling to determine the isotopic composition of O, H, S, C, N, and He in highly magmatic, arc type volcanic gases and investigate the effects of temperature on the isotopic compositions; (3) make inferences on the ultimate origins of the rare metals using obtained data; and (4) measure SO2 flux from other volcanoes nearby on the Kurile Arc: Baranski, Ivan Grozniy, and Burevestnik. This proposed research in geological sciences fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Russia to combine complementary talents and pool research resources in areas of strong mutual interest and competence. The workshop will also be used to promote the interest of graduate and undergraduate students in particle physics. ***
