A Conference on "Low-18O Rhyolites and Crustal Melting: Growth and Redistribution of the Continental Crust"

这一奖项将支持几位职业生涯早期的参与者出席GSA彭罗斯会议，题为“低三角洲18O流纹岩和地壳熔融：大陆地壳的生长和再分布”。低三角洲18O流纹岩很重要，因为氧通常占火成岩的50%左右，长期以来人们一直注意到，只有在岩浆形成和演化期间进行的重大过程才能产生这些异常的三角洲18O值。因此，对这些岩浆的研究等同于对基本大陆过程的研究，并提供了对地壳内部质量增长和再分配的洞察。这次研讨会讨论了一个及时的主题，并被美国地质学会选为2009年秋季的赞助商。这一奖励将有助于抵消研究生和博士后研究员参加这次会议的费用，否则他们将无法参加这次会议。会议领导人召集了广泛的国际研究人员，他们对了解大陆地壳的这些独特探测具有科学兴趣，并为流纹岩岩浆形成和大陆地壳演化的研究做出了贡献。由于蛇河平原/黄石岩浆在现代低三角洲18O流纹岩研究中的优势，会议将在这一领域附近举行。大约20%的会议时段将向来自美国和国外的学生和博士后研究员开放。该奖项将支持其中至少20个项目。

This award will support the attendance of several early-career participants in the GSA Penrose conference entitled "Low delta 18O rhyolites and crustal melting: Growth and redistribution of the continental crust". Low delta 18O rhyolites are important because, as oxygen generally makes up about 50 mole percent of igneous rocks, it has long been noted that only significant processes that operate during the genesis and evolution of magmas can act to produce these anomalous delta 18O values. Therefore, the study of these magmas equates to a study of fundamental continental processes and provides insight on the growth and redistribution of mass within the crust itself.This workshop addresses a timely topic and has been selected to be sponsored by the Geological Society of America for the Fall of 2009. This award will help offset the expenses for the participation of graduate students and post-doctoral fellows who would not otherwise be able to attend this conference. The leaders of the conference have convened a broad spectrum of international researchers who have scientific interests that bear on the understanding of these unique probes of the continental crust, and who have contributed to the study of rhyolite magma formation and continental crustal evolution. Because of the preeminence of Snake River Plain/Yellowstone magmas in modern low delta 18O rhyolite research, the conference will take place close to this field area. Approximately 20 percent of the conference slots will be open for students and post-doctoral fellows not only from the United States but also from abroad. This award will support at least 20 of them.
