项目摘要

0405573NaslundDr. H. Richard Naslund, State University of New York, Binghamton, along with Dr. Fernando Henriquez, University of Santiago, will hold a workshop and field excursion to the volcano in El Laco, Chile in the Fall of 2004. Support comes from the Office of International Science and Engineering (OISE) and the Petrology and Geochemistry Program.The El Laco volcano in the Andean Cordillera of northern Chile contains the youngest, least altered and best preserved magnetite-apatite ores of Kiruna-type. Dr. Naslund will assemble scientists to participate in a workshop to examine the El Laco deposit in the field and then to discuss the various models that have been proposed for its origin. There is an ongoing scientific debate about the origin of a particular class of ore deposits. If ion oxide rich magmas have erupted at even one locality on Earth, scientists need to consider the effects such magmas might have on many other geologic processes in addition to the formation of ore deposits. The formation of stratified ore deposits by Fe-oxide magmas or by hydrothermal replacement might also have implications for the formation of recently identified fragmental hematite deposits on Mars. This award will provide support for students and researchers in the early stages of their career to attend this meeting which will be held along-side of the larger IAVCEI General Assembly meeting in nearby Pucon, Chile

0405573纳斯伦德博士。纽约州立大学宾厄姆顿分校的 H. Richard Naslund 与圣地亚哥大学的 Fernando Henriquez 博士将于 2004 年秋季举办研讨会并前往智利埃尔拉科火山进行实地考察。办事处提供支持国际科学与工程 (OISE) 和岩石学与地球化学项目。位于智利北部安第斯山脉的埃尔拉科火山拥有最年轻、变化最小且保存最完好的火山基律纳型磁铁矿-磷灰石矿石。纳斯伦德博士将召集科学家参加一个研讨会，在现场检查埃尔拉科矿床，然后讨论为其起源提出的各种模型。关于特定类别矿床的起源，科学界一直存在争论。如果富含离子氧化物的岩浆在地球上的一处喷发，科学家们就需要考虑除了矿床形成之外，这种岩浆可能对许多其他地质过程产生的影响。由氧化铁岩浆或热液置换形成的分层矿床也可能对最近在火星上发现的碎片赤铁矿矿床的形成产生影响。该奖项将为职业生涯早期阶段的学生和研究人员提供支持，以参加本次会议，该会议将与在智利普孔附近举行的大型 IAVCEI 大会同时举行
