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

0405573NaslundDr. H. 2004年秋季，纽约宾厄姆顿州立大学的Richard Naslund将与圣地亚哥大学的Fernando Henriquez博士一起沿着举办一个讲习班，并到智利埃尔拉科火山进行实地考察。 智利北方安第斯山脉的埃尔拉科火山含有最年轻、变化最少和保存最好的基律纳型磁铁矿-磷灰石矿石。 Naslund博士将召集科学家参加一个研讨会，在实地检查El Laco存款，然后讨论已提出的各种模型，其起源。 关于某一类矿床的起源，科学界一直在争论不休。 如果富含离子氧化物的岩浆在地球上的一个地方爆发，科学家们需要考虑这些岩浆除了形成矿床外，还可能对许多其他地质过程产生的影响。 铁氧化物岩浆或热液置换形成的层状矿床也可能对最近在火星上发现的碎裂赤铁矿矿床的形成产生影响。 该奖项将为处于职业生涯早期阶段的学生和研究人员提供支持，以参加将在智利普孔附近举行的更大的IAVCEI大会会议
