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 naslunddr。纽约州立大学宾厄姆顿分校的H. Richard Naslund和圣地亚哥大学的Fernando Henriquez博士将于2004年秋天在智利的El Laco举行一次研讨会和实地考察。支持来自国际科学与工程办公室（OISE）和岩石学和地球化学计划。智利北部安第斯山脉的El Laco火山含有最年轻、蚀变最少、保存最完好的基鲁纳型磁铁矿-磷灰石矿石。纳斯伦德博士将召集科学家参加一个研讨会，在实地考察埃尔拉科矿床，然后讨论提出的关于其起源的各种模型。关于一类特殊矿床的起源，科学界一直存在争论。如果富含氧化离子的岩浆在地球上的一个地方喷发，科学家们需要考虑这些岩浆除了对矿床的形成之外，还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替代形成的层状矿床也可能对最近在火星上发现的块状赤铁矿矿床的形成产生影响。该奖项将支持处于职业生涯早期阶段的学生和研究人员参加本次会议，该会议将与在智利普孔附近举行的更大的IAVCEI大会同时举行
