IRES: Unraveling the complex volcanic history of the Noumea Basin, New Caledonia

ABSTRACTProposal没有。项目名称：NICHOLSON， Kirsten N.PI所在机构：波尔州立大学项目名称：IRES：解开新喀里多尼亚努美阿盆地复杂的火山历史这个国际学生研究经验（IRES）项目将支持波尔州立大学（BSU）和当地本科机构的美国本科生和研究生。学生们将在新喀里多尼亚与来自新喀里多尼亚大学、新喀里多尼亚大学和奥克兰大学的研究科学家一起进行研究。这是一个为期三年的研究努美阿盆地的项目，涉及多达14名本科生和一名硕士学生。研究的目的是将基本的地质填图技术与现代地球化学分析相结合，确定盆地的火山历史。这项工作将确定火山作用的性质、风格、范围和年龄，以及各单元（基性和长质）之间可能的关系，以便更好地了解产生火山作用的过程。此外，还将探讨冈瓦纳东部边缘的活动构造过程。一旦建立了努美阿盆地火山历史的模型，研究结果将用于调查白垩纪晚期火山灾害对该地区可能产生的影响（如可能的灭绝、气候变化、排水变化等）。最后，这项工作的结果将与新西兰、澳大利亚和南极洲的发现相结合，以进一步了解该地区的火山作用和负责岩浆产生的构造过程。这项研究将为本科生和研究生提供与来自世界各地的科学家一起参与研究的机会；具有国际文化经验，批判性思维机会以及实地和实验室实践经验。这个项目将成为美国、法国、新西兰和新喀里多尼亚科学家之间关于沉积学、火山学、火成岩和变质岩石学、地球物理学和大区域构造学的进一步国际科学项目的基础。期望为研究生和本科生提供更多的合作机会、资助机会、文化意识和研究机会。此外，更好地了解火成岩和沉积单元的构造历史和变质作用，可能对镍金矿广泛开采地区的勘探和勘探策略具有指导意义。

ABSTRACTProposal No.: 0727323PI Name: NICHOLSON, Kirsten N.PI's Institution: Ball State UniversityProposal Title: IRES: Unraveling the complex volcanic history of the Noumea Basin, New CaledoniaThis International Research Experiences for Students (IRES) project will support U.S. undergraduate and graduate students from Ball State University (BSU) and local undergraduate institutions. The students will conduct research in New Caledonia with research scientist from the Bureau de Geologie de la Nouvelle-Caledonie, the University of New Caledonia, and the University of Auckland. This is a three year project to study the Noumea Basin involving up to fourteen undergraduate students and one MSc student.The goal of the research is to determine the volcanic history of the basin by combining basic geologic mapping techniques with modern geochemical analyses. This work will identify the nature, style, extent and age of volcanism, in addition to possible relationships between the units (both mafic and felsic) in order to better understand the processes responsible for generating the volcanism. The active tectonic processes along the eastern Gondwana margin will also be explored. Once a model for the volcanic history of the Noumea Basin is constructed, the results of the study will then be used to investigate the possible effects of volcanic hazards on the region during the late Cretaceous (such as possible extinctions, climate changes, changes in drainage etc). Finally the results of this work will be combined with findings in New Zealand, Australia and Antarctica to further our understanding of volcanism within the region and the tectonic processes responsible for magma generation.This research will provide undergraduate and graduate students the opportunity to participate in research with scientists from around the world; international cultural experiences, critical thinking opportunities and hand-on field and laboratory experience. This project will be the basis of further international scientific projects between scientists in the U.S.A., France, New Zealand and New Caledonia on sedimentology, volcanology, igneous and metamorphic petrology, geophysics and tectonics of the greater region. Increased opportunities are expected for future collaborations, funding opportunities, cultural awareness, and research opportunities for graduate and undergraduate students. In addition, a better understanding of the tectonic history and metamorphism in the igneous and sedimentary units may have implications for exploration and exploration strategies in an area of extensive nickel and gold mining.
