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.

新墨西哥高地大学 (NMHU) 计划在资助期内每年让至少 5 名美国本科生/研究生在捷克共和国和波兰从事地质领域和实验室工作 5 周以上（总共 15 周以上）。 （大多数西班牙裔、美洲原住民和女性）是 NSF 提高 STEM 代表性的目标人群。该项目将通过培训和促进代表性不足的学生的研究来推进 NSF 的使命，并服务于 NMHU 提供学生研究的使命。学生国际研究体验（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。这些学生融入项目范围将为充分认识科学方面带来新的视角，并直观地传达 IRES 第二阶段的社会影响。该工作计划将进一步平衡科学探究和学生培训的需求。 NMHU 的声誉 – 新墨西哥州首屈一指的西班牙裔学生该研究合作利用 PI 和导师的专业知识，使用多样化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。与该地区的文化遗产交织在一起的实体和数字媒体产品将与公众分享，详细说明如何以及为何进行地质研究，并记录令人兴奋的地质发现。I​​RES 第二阶段研究工作的目标是仔细研究岩浆-深成系统的根源、驱动构造的各个方面以及由此产生的沉积作用，IRES第一阶段研究（2017-2022）为浅层岩浆系统（1公里）的生长、演化和变形提供了重要的约束。 IRES 第二阶段重点关注更深的岩浆管道和就位系统（2-10 公里深度）以及碎屑、湖泊和河流沉积物的暴露窗口我们的方法包括：1) 火成岩和沉积岩结构的初步现场观测、结构测量以及岩石学、古地磁和岩石磁力分析的样品采集；2) 地球物理调查，以绘制地下和结构图。每位导师的专业知识和 NMHU、捷克共和国、波兰和波兰的实验室设施都可以为美国 IRES 学生提供支持。拟议的活动将探索创造性和变革性的先进概念。通过询问以下问题，我们可以了解岩浆-深成系统的知识：我们是否在岩浆系统的“深层”部分看到了垂直或横向的岩浆流动？我们是否看到了从岩浆到构造的结构方向的变化以及在什么结构水平上的变化？与构造和沉积相关的问题包括： 早古生代后瓦里斯盆地的构造和沉积背景是什么？捷克共和国？碎屑成分是否表明了当地的物源或更多的区域性烃源岩？ IRES 第二阶段将提供有关这些和其他研究主题的关键数据。地质研究的多学科方法，培养具有重要可转移技能（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，并让学生参与挑战长期存在的造山运动模型的合作研究，该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
