IRES: From the Roots to the Roof - the Anatomy of the Volcanic-Magmatic-Plutonic System

火山系统的近地表顶板通常被认为是地质上简单的。熔岩从深处喷发，从地表流出。该项目研究了该系统的演变是否更为复杂，随着时间的推移，熔融岩石的多次注入垂直和横向地向火山的中央喷口方向和方向输送。这些模式的记录可能表明，这种更复杂的模型可能是常态，从而导致地球上最丰富的火山结构的革命性发现。该项目还将研究火山系统根部的主要特征是否经常被保存下来，为追踪火山系统深层的生长提供一种机制。至少有15名来自新墨西哥高地大学（西班牙裔服务机构）和其他参与的大学（也是西班牙裔服务机构）的学生将研究捷克共和国的火山系统，以实现从火山深层根部到近地表屋顶的全面解剖特征的项目目标。地质学研究生和本科生将通过与国际地质学家团队合作来扩展他们的研究技能。一个由来自少数族裔背景的媒体艺术系学生组成的小组将记录该项目，通过公共宣传项目与广大受众分享国际研究的总体经验。通过这个为期3年的项目，本科生和研究生将使用独特的多学科方法进行地质调查，包括实地和实验室研究，以更好地理解和挑战长期存在的火山生长模型。在积累研究经验的同时，学生将加深对火山解剖学的了解。在捷克共和国中部波西米亚天堂（Èeský ráj）的Jièín火山区，从中世纪到今天的自然侵蚀和采石活动已经挖掘出许多火山，暴露在火山原表面以下100米至4公里的高度。与来自捷克共和国、法国和波兰的导师合作，学生们将解释岩浆流动模式，以及岩脉侵入、隐穹形成和岩浆在地表爆发的物理过程。就该系统的根源而言，学生将重点关注布拉格附近和捷克共和国东北部暴露良好、被深度侵蚀的火山-深成系统。项目团队将采用以下方法：1)主要野外观测、结构测量、岩石学、经济矿床成因、古磁学和各向异性磁化率分析的样品收集；2)地球物理测量，绘制地下构造图。团队专家贡献的技能包括物理火山学、火山地层学、地球化学、勘探地球物理、岩浆就位力学、构造地质学和经济矿化。总的来说，这些分析工具将用于在野外和实验室环境中评估火山系统。让未被充分代表的媒体艺术学生参与记录学习和研究过程的技能，将有助于培养下一代媒体艺术和地质学学生，向他们灌输全球竞争力。该项目由地球科学部地球科学理事会共同资助。

The near-surface roof of volcanic systems is often considered geologically simple. Lava erupts from depth and flows out at the surface. This project examines whether the evolution of the system is more complex, with multiple injections of molten rock over time transported vertically and laterally toward and away from the central vent of the volcano. Documentation of these patterns could indicate that this more complex model may be the norm, leading to a transformative discovery of the most abundant volcanic constructs on Earth. The project will also study whether primary features of the roots of volcanic systems are often preserved, providing a mechanism to track the growth of the deeper parts of the volcanic system. At least 15 students from New Mexico Highlands University - a Hispanic Serving Institution - and other participating universities - also Hispanic Serving Institutions - will study volcanic systems in the Czech Republic to achieve the project goal of fully characterizing the anatomy of volcanoes from the deep roots to the near-surface roof. Geology graduate and undergraduate students will expand their research skills by working collaboratively with an international team of geologists. A small team of media arts students from underrepresented backgrounds will document the project to share the overall experience of international research with a broad audience through public outreach programs. Through this 3-year project, undergraduate and graduate students will use a unique multidisciplinary approach to geologic investigation that involves field- and laboratory-based research to better understand and challenge long-standing volcano growth models. While building their research experience, the students will advance understanding of volcano anatomy. In the Jièín Volcanic Field in the Central Bohemian Paradise (Èeský ráj), Czech Republic, natural erosion and quarrying activities from medieval times through today have unearthed many volcanoes to expose levels between 100 m to 4 km below the original surface of the volcano. Teamed with mentors from the Czech Republic, France, and Poland students will interpret the magma flow pattern, as well as the physical process of dike intrusion, cryptodome formation, and magma breakout at the surface. In terms of the roots of the system, students will focus on well-exposed, deeply eroded volcanic-plutonic systems near Prague and in the northeast Czech Republic. The project team will use methods such as: 1) primary field observations, structural measurements, sample collection for petrology, economic ore genesis, paleomagnetic, and anisotropy of magnetic susceptibility analysis; and 2) geophysical surveys to map the subsurface structure. Team experts contribute skills sets including physical volcanology, volcanostratigraphy, geochemistry, exploration geophysics, magma emplacement mechanics, structural geology, and economic ore mineralization. Collectively, these analytical tools will be used to evaluate the volcanic system in the field and a laboratory setting. Engaging the skills of underrepresented media arts students in documenting the learning and research process will contribute to building the next generation of media arts and geology students, instilling in them a sense of global competency.This project is co-funded by the Directorate for Geosciences, Division of Earth Sciences.
