IRES Track 1: International Research Experiences for Students: Phase II: Into the Magmatic Roots: Interactions Between Magmatism, Tectonics, and Sedimentation

新墨西哥高地大学(NMHU)计划在资助期内每年聘用至少5名美国本科生/研究生5周以上(共15名以上学生)，在捷克共和国和波兰从事地质野外和实验室工作。受影响的学生(主要是西班牙裔、印第安人和女性)是NSF的目标，目的是增加STEM的代表性。该项目将通过培训和促进代表不足的学生的研究来推进NSF的使命，并为NMHU提供学生研究机会的使命服务。国际学生研究体验(IRES)第二阶段的一个独特计划是，每年支持一名美术和/或媒体艺术研究生与队列一起旅行，记录旅行中的地质活动和文化方面。将这些学生纳入项目范围将带来新的视角，充分认识到IRES第二阶段的科学方面，并直观地传达其社会影响。该工作计划平衡了科学研究和学生培训的需要。这将进一步提高新墨西哥州首屈一指的拉美裔服务机构NMHU的声誉。该研究合作利用了PI和导师的专业知识，使用不同的工具集来研究地球系统过程。拟议的活动将探索创造性和变革性的概念，增进我们对古代火山系统的了解，并了解自然环境如何与该区域的文化遗产交织在一起。这些实物和数字媒体产品将与公众分享，详细说明如何以及为什么进行地质研究，并记录地质发现的兴奋之处。IRES第二阶段研究的目标是仔细研究岩浆-深成体系的根源、驱动构造的各个方面，以及由此产生的沉积作用。IRES第一阶段调查(2017-2022年)为浅层岩浆系统(1公里)的生长、演化和变形提供了重要的制约因素。IRES第二阶段的重点是接触到更深的岩浆管道和侵位系统(深度2-10公里)的窗口，以及火山构造活动沉积的碎屑、湖泊和河流沉积物。我们的方法包括：1)火成岩和沉积组构的初步野外观测，构造测量，岩石学、古地磁和岩石磁性分析的样品收集，以及2)地球物理调查，以绘制地下结构图并提供整体解释。每位导师的专业知识和位于捷克和波兰的NMHU的实验室设施将可用于支持美国IRES的学生。拟议的活动将探索创造性和变革性的概念，通过以下问题来促进我们对岩浆-深成系统的了解：我们在岩浆系统的“深层”部分是否看到垂直或横向的岩浆流动？我们是否看到了从岩浆到构造的组构方向的变化，以及在什么构造层面上(S)？与构造和沉积有关的问题包括：早古生代华力西后盆地的构造和沉积环境是什么？与捷克埃格尔地块有关的新近系沉积的性质是什么？碎屑成分是否表明了当地的物源或更具区域性的生油岩？沉积相能否作为约束断层错动的切入点？IRES第二阶段将提供有关这些和其他研究主题的关键数据。该项目将使学生接触到地质研究的多学科方法，培养具备重要可转移技能(批判性思维、沟通、多元数据分析和全球能力)的下一代地球科学家，并让学生参与挑战造山运动、火成岩活动的长期模型以及选择波希米亚部分地区沉积史的合作研究。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

New Mexico Highlands University (NMHU) plans to engage at least five U.S. undergraduate/graduate students for 5+ weeks per year over the grant period (15+ students total) in geology field and laboratory work in the Czech Republic and Poland. The impacted students (majority Hispanic, Native American and female) are among those targeted by NSF for increasing representation in STEM. This project will advance the mission of NSF by training and fostering research for underrepresented students and serve NMHU's mission to provide student research opportunities. A distinctive scheme of the International Research Experience for Students (IRES) Phase II is that it involves supporting a Fine Art and/or Media Arts graduate student each year to travel with the cohort to document the geologic activities and cultural aspects of the travel. The mixing of these students into the scope of the project will bring a fresh perspective to fully realize the scientific aspects and to visually communicate the societal impacts of IRES Phase II. The work plan balances the needs of scientific inquiry and student training. It will further the reputation of NMHU – New Mexico's premier Hispanic serving institution. The research collaboration capitalizes on the expertise of the PIs and mentors to study earth system process using a diverse tool set. The proposed activities will explore creative and transformative concepts advancing our knowledge of the ancient volcanic systems and understanding how the natural environment is intertwined with the cultural heritage of the region. The physical and digital media products will be shared with the general public to detail how and why geologic research is conducted and document the excitement of geologic discovery.The objectives of the IRES Phase II research endeavors are to scrutinize the roots of the magmatic-plutonic system, aspects of the driving tectonics, and resultant sedimentation. IRES Phase I investigations (2017-2022) provided important constraints on the growth, evolution, and deformation of the shallow magmatic systems (1 km). IRES Phase II focuses on windows of exposure into the deeper magmatic plumbing and emplacement system (2-10 km depth) along with clastic, lacustrine, and fluvial sediments deposited due to the volcanic-tectonic activity. Our methods include: 1) primary field observations of igneous and sedimentary fabrics, structural measurements, and sample collection for petrologic, paleomagnetic, and rock magnetic analysis and 2) geophysical surveys to map the subsurface structure and inform overall interpretations. Each mentor's expertise and the laboratory facilities at NMHU, Czech Republic, and Poland will be accessible to support the U.S. IRES students. The proposed activities will explore creative and transformative concepts advancing our knowledge of the magmatic-plutonic system by asking: Do we see vertical or lateral magma flow in the "deep" part of the magmatic system? Do we see a change in fabric orientation from magmatic to tectonic and at what structural level(s)? Questions related to tectonics and sedimentation include: What are the tectonic and depositional settings of the post Variscan basins during the early Paleozoic? What is the nature of Neogene sedimentation associated with the Eger graben in Czech Republic? Do clast compositions indicate a local provenance or a more regional source rock? Can depositional facies be used as piercing points for constraining fault offset? IRES Phase II will provide critical data on these and other research topics. The project will expose students to multidisciplinary approaches to geologic research, build the next generation of geoscientists poised with important transferable skills (critical thinking, communication, multivariate data analysis, and global competency), and involve students in collaborative research that challenges long-standing models of orogeny, igneous activity, and select depositional histories in parts of Bohemia.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
