项目摘要

Large igneous provinces, like the Snake River Plain in Washington State or the Deccan Traps of India, represent huge outpourings of basalt from the mantle and are prominent geologic features of the land and seafloor. Due to their immense size and the vast amount of reduced fluids and other volatiles they release upon eruption, these eruptive sequences have major impacts on local and global environmental and atmospheric conditions. The Ontong Java Plateau in the Pacific Ocean is one of these provinces and was erupted almost entirely underwater where it affected global ocean chemistry. This research develops novel new methods for determining the length, volume, duration, style, and depth of lava flow emplacement at Ontong Java. Samples of basaltic glasses from cores collected by the Ocean Drilling Program will be analyzed for volatile species (Cl, S, H2O, CO2) by very precise electron microprobe, FTIR, and laser ablation ICPMS. Major and trace elements will also be analyzed. Statistical methods will be used to determine if different samples are from the same flow field and/or eruption. Samples both within and between drill holes will be compared. Goals are to determine if individual lava flows can be traced hundreds of kilometers and to use this information to constrain lava flow size and emplacement rates. The broader impacts of the work include a large service-learning component that will engage undergraduates with K-12 students, as well as carry out an innovative simulated oceanographic voyage that will integrate research and education and impact over 100 undergraduates. In terms of other workforce development, a graduate student will be trained and students will be taken to professional society meetings to present the results of their work. Additional impacts include the fact that funds will be provided to an institution in an EPSCoR state (Oklahoma), international collaboration with German scientists, and the interlaboratory calibration of volatile data. Results of the work are complementary to those of the NSF-funded Ocean Drilling Program.
大型火成岩区,如华盛顿州的蛇河平原或印度的德干地陷,代表了地幔中大量玄武岩的涌出,是陆地和海底的突出地质特征。 由于其巨大的规模和大量的还原流体和其他挥发物,他们释放的喷发,这些喷发序列对当地和全球的环境和大气条件产生重大影响。 位于太平洋的Ontong Java高原就是其中之一,几乎完全在水下爆发,影响了全球海洋化学。 这项研究开发了新的新方法,用于确定Ontong Java熔岩流侵位的长度,体积,持续时间,风格和深度。 将通过非常精确的电子微探针、傅里叶变换红外光谱仪和激光烧蚀等离子体质谱仪分析大洋钻探计划收集的岩芯中的玄武岩玻璃样品中的挥发性物质(Cl、S、H2O、CO2)。 还将分析主要和微量元素。 将使用统计方法确定不同样本是否来自相同的流场和/或喷发。 将比较钻孔内和钻孔之间的样本。 目标是确定单个熔岩流是否可以追踪数百公里,并使用此信息来限制熔岩流的大小和就位率。 这项工作的更广泛的影响包括一个大型的服务学习组件,将使本科生与K-12学生接触,以及进行创新的模拟海洋学航行,将研究和教育结合起来,影响100多名本科生。 在其他劳动力发展方面,将培训一名研究生,并将带学生参加专业协会会议,介绍他们的工作成果。 其他影响包括将向EPSCoR州(俄克拉荷马州)的一个机构提供资金,与德国科学家进行国际合作,以及对不稳定数据进行实验室间校准。 这项工作的结果是对NSF资助的海洋钻探计划的补充。
