IRES: Closing Oceans: Assessing the Dynamics of Turkish suture zonesPI: Catlos, co-PI: Elliott, KylePART 1:This International Research Experiences for Students (IRES) program provides four weeks of geological field-based research and training experiences across Turkey for 12 US students. Over the next 3 years, these students will investigate suture zones,i.e.locations where ancient ocean basins closed across the country. Turkey contains a large number of these zones, which are key locations used by geologists to understand how continents grow. Continental growth is considered one of the most important problems facing Earth Scientists, yet models for the process are debated, due in part to a lack of geologic record. Because of its extensive outcrops of ancient rocks associated with suture zones, Turkey is an ideal location to study this process.The IRES program has societal value, as Turkey's suture zones can be associated with important ore and mineral resources or are regions of major, present-day geologic hazards. Older faults that worked to close the ocean basins today form regions of active earthquake activity or have generated topography that leads to large landslides. Understanding the locations and ages of Turkey's ancient suture zones has an impact on diverse topics, including mineral exploration and hazard reduction. This proposal includes partnerships with faculty at three Turkish universities (Dokuz Eylul University, Middle East Technical University, and Karadeniz Technical University) who will serve as mentors. Students chosen to participate are underrepresented in the geosciences and are selected via Jackson School and UT Austin outreach programs. Students will partner with Turkish researchers to explore a range of geological concepts discussed in their courses while making a significant impact on our understanding of processes related to the formation of continental crust. Students will apply innovative methods to address scientific questions involving both the timing and impacts of Turkey's suture zones, including electronic-based field mapping techniques and new geochemical approaches. This in turn will lead to insight into how the past geological history of Turkey impacts its present day concerns, including the development of economically important resources and hazard mitigation. PART 2:Understanding how continents grow is recognized as one of the most important geodynamic problems facing Earth Scientists. Models for the process are debated, due in part to a lack of exposure of the geologic record. Because of its extensive exposures of ancient ocean suture zones and crustal fragments, Turkey is an ideal location to study this process. This International Research Experiences for Students (IRES) program provides four weeks of geological field-based research and training experiences across Turkey for 12 US students. Over the next 3 years, these students will investigate the arc accretion processes that occurred in Turkey during the closure of branches of ancient ocean basins.In addition, the IRES program has societal value, as paleogeographic reconstructions are used to identify important economic resources that formed during specific times in Earth's history and assess geologic hazards that result due to reactivation of older faults or mass movement of rocks. This proposal includes partnerships with faculty at 3 Turkish universities (Dokuz Eylul University, Middle East Technical University, and Karadeniz Technical University) who will serve as mentors. Students chosen to participate are underrepresented in the geosciences and are selected via Jackson School and UT Austin outreach programs. Students will partner with Turkish researchers to explore a multidisciplinary range of geological concepts discussed in their courses while making a significant impact on our understanding of processes related to the formation of continental crust. Students will apply new and innovative field mapping, geochemical, and geochronological methods, lending greater insight into the history and mechanics of the assembly of Turkey.

IRES：封闭海洋：评估土耳其缝合带的动态PI：Catlos，co-PI：Elliott，KylePART 1：这个学生国际研究体验(IRES)项目为12名美国学生提供为期四周的土耳其地质实地研究和培训体验。在接下来的三年里，这些学生将研究缝合带，即全国古代洋盆闭合的地方。土耳其有大量这样的地带，地质学家利用这些地带来了解大陆是如何生长的。大陆增长被认为是地球科学家面临的最重要的问题之一，但这一过程的模型存在争议，部分原因是缺乏地质记录。由于与缝合带相关的古老岩石的广泛露头，土耳其是研究这一过程的理想地点。IRES项目具有社会价值，因为土耳其的缝合带可能与重要的矿石和矿产资源有关，或者是当今重大地质灾害的地区。今天关闭洋盆的较老的断层形成了活跃的地震活动区，或者形成了导致大型山体滑坡的地形。了解土耳其古代缝合带的位置和年代对包括矿产勘探和减灾在内的各种主题都有影响。这项建议包括与土耳其三所大学(多库兹埃吕尔大学、中东技术大学和卡拉达尼兹技术大学)的教师建立伙伴关系，他们将担任导师。被选中参与的学生在地球科学领域的代表性不足，他们是通过杰克逊学校和德克萨斯大学奥斯汀分校的推广项目挑选出来的。学生将与土耳其研究人员合作，探索他们课程中讨论的一系列地质概念，同时对我们理解与大陆地壳形成有关的过程产生重大影响。学生将应用创新的方法来解决涉及土耳其缝合区的时间和影响的科学问题，包括基于电子的野外测绘技术和新的地球化学方法。这反过来将导致洞察土耳其过去的地质历史如何影响其当今的关切，包括开发重要的经济资源和减灾。第二部分：了解大陆是如何生长的被认为是地球科学家面临的最重要的地球动力学问题之一。对这一过程的模型存在争议，部分原因是缺乏对地质记录的曝光。由于土耳其广泛暴露于古代海洋缝合带和地壳碎片，是研究这一过程的理想地点。这项面向学生的国际研究体验(IRES)项目为12名美国学生提供为期四周的土耳其地质实地研究和培训体验。在接下来的三年里，这些学生将研究在土耳其古代洋盆分支关闭期间发生的弧形沉积过程。此外，IRES计划具有社会价值，因为古地理重建被用来识别在地球历史上特定时期形成的重要经济资源，并评估由于较老断层的重新激活或岩石的大规模运动而造成的地质灾害。这项建议包括与3所土耳其大学(多库兹埃吕尔大学、中东技术大学和卡拉达尼兹技术大学)的教师建立伙伴关系，他们将担任导师。被选中参与的学生在地球科学领域的代表性不足，他们是通过杰克逊学校和德克萨斯大学奥斯汀分校的推广项目挑选出来的。学生将与土耳其研究人员合作，探索他们课程中讨论的一系列多学科的地质概念，同时对我们理解与大陆地壳形成有关的过程产生重大影响。学生将应用新的和创新的野外测绘、地球化学和地质年代学方法，更深入地了解土耳其议会的历史和机制。
