Magma (molten rock) typically forms between 75 and 150 km below Earth’s surface (in the Earth’s mantle) and either stalls and cools in the upper 35-50 km (the Earth’s crust) or erupts to form a volcano. Understanding how magmas change physically and chemically informs an array of societally important topics from how, when, and where a volcano might erupt to the formation of economically important resources. These changes are documented by a computer tool called the Magma Chamber Simulator that was developed by the Principal Investigators. Funding provided by this grant for advancements to the Magma Chamber Simulator will enhance geologists’ ability to address a range of questions, such as where magmas form and cool in the Earth’s interior, how magmas evolve from Hawaiian-like to Yellowstone-like compositions, and what magma gas content might be, which potentially controls the explosivity that might occur, with obvious societal implications. This information provides data for volcanologists to better predict volcanic eruptions and assess the volcanic hazards that impact the health, safety, and livelihood of millions of people. Changes to the Magma Chamber Simulator involve adding additional mathematical approaches to how magmas change, updating and verifying a complex computer code, and running computer models on particular groups of volcanic rocks to address typical questions. The Magma Chamber Simulator is a free computer modeling tool that is available to anyone and thus provides capability for beginning students to experienced professionals to learn about how magmas change as they move from inside the Earth to the surface. Funding will provide opportunities for students and early career professionals to learn about computer modeling and the benefits it provides for advancing scientific understanding of a range of geologic topics. Training activities, from beginning to advanced level, will be provided both online and in person. Funding will also support advanced educational training for diverse students who will enter the earth science work force, which in the coming decades is key to addressing solutions to many of the hazard and resource challenges humans face. This funding will support substantial advances the petrologic community’s capability to model open system magma evolution for translithosphere magma systems by adding significant keystone functionality to the publicly available tool, the Magma Chamber Simulator (MCS). The new tool, called Translithosphere Magma Chamber Simulator (TL-MCS) utilizes the capabilities of MCS, a thermodynamic model that quantifies the evolution of an open system where magma, wallrock, and recharge/stoping/entrainment reservoirs exchange matter and energy. MCS models simultaneous crustal contamination, magma recharge, cumulate/mush entrainment, and fractional crystallization. Five new capabilities to TL-MCS include: (i) transport of a fluid phase from wallrock to magma; (ii) radiogenic isotopic disequilibrium during wallrock melting; (iii) equilibrium crystallization of resident magma; (iv) reaction of earlier formed crystals and resident magma; and (v) translithosphere modeling functionality (i.e., polybaric, polybaric-isobaric modeling capability). New post-processing capabilities will enhance and accelerate interpretation of results of TL-MCS models; Jupyter notebooks (using Python) will include (i) user-friendly statistical techniques that inform the choice of ‘best fit’ models, and (ii) new algorithms for efficient data archiving and user ‘on-demand’ plotting. Widespread distribution and use of TL-MCS are top priorities. Funding will support strategies for sharing TL-MCS and training users that include continuous updates to the MCS website, online and in person workshops, and online tutorials offered in English and Spanish. Because TL-MCS has complex functionality, additional training for advanced users will focus on effective and efficient modeling strategies and include publication of a roadmap of effective modeling practices. Application of TL-MCS to igneous localities worldwide will enable diverse researchers to explore the open system translithosphere evolution of these systems. Funding for diverse students and post-doctoral researchers will support their scientific and professional development and position them to join the earth science workforce as highly trained computer modelers. Opportunities will include designing and executing research projects and tutorials, writing proposals, leadership roles in workshops and tutorial development, oral presentations, peer-reviewed publications, and development of professional networks. Finally, increased opportunity for engagement in open system processes research will be available via an online world-wide open system magma processes working group that the funded scientists will initiate and manage.This project is co-funded by a collaboration between the Directorate for Geosciences and Office of Advanced Cyberinfrastructure to support AI/ML and open science activities in the geosciences.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.

岩浆（熔融岩石）通常形成地球表面以下75至150公里（在地球地幔中），在35-50 km的上部（地壳）中降低并冷却以形成火山。了解岩浆在物理和化学上如何变化，从何时，何时和何处爆发到经济上重要的资源的形成，从何时，何时和何处介绍了一系列具有社会重要的主题。这些更改是由主要研究人员开发的称为岩浆室模拟器的计算机工具记录的。该赠款为岩浆室模拟器提供的资金提供的资金将增强地质学家解决一系列问题的能力，例如地球内部形成岩浆和凉爽的地方，岩浆从夏威夷式形成到类似夏威夷式的构图，以及类似黄石般的构图，以及可能是什么爆炸性，可能会发生的爆炸性。该信息为火山学家提供了数据，以更好地预测火山喷发并评估影响数百万人的健康，安全和生计的火山危害。岩浆腔室模拟器的更改涉及添加其他数学方法，以了解岩浆如何更改，更新和验证复杂的计算机代码以及在特定的火山岩组上运行计算机模型以解决典型问题。岩浆室模拟器是一种免费的计算机建模工具，可供任何人使用，因此为初学者提供了体验专业人士的能力，以了解岩浆从地球内部移动到地面时如何变化。资金将为学生和早期职业专业人员提供机会，以了解计算机建模及其为推进一系列地质主题的科学理解所带来的好处。从开始到高级的培训活动将在线和亲自提供。资金还将为将进入地球科学劳动力的潜水员学生提供高级教育培训，在未来几十年中，这是解决许多危害和资源挑战的解决方案的关键。这项资金将支持岩石学界通过为公开可用的工具（MAGMA室模拟器（MCS））添加明显的Keystone功能来建模岩石岩浆系统开放系统岩浆演变的能力。新工具称为Translithosphere Magma腔室模拟器（TL-MCS），利用MC的功能，MCS是一种热力学模型，量化了开放系统的演变，其中岩浆，壁挂和补给/停止/停止/夹带/夹带/夹杂物储层交换物质和能量。 MCS模型同时构成了地壳污染，岩浆补给，累积/糊入口和分数结晶。 TL-MC的五个新功能包括：（i）从壁岩到岩浆的流体相传输； （ii）壁挂式熔化期间的放射同位素二动； （iii）等效的岩浆结晶； （iv）早期形成的晶体和居民岩浆的反应； （v）转化层建模功能（即多巴罗里克，多巴拉克 - 质体建模能力）。新的后处理能力将增强和加速对TL-MCS模型结果的解释； Jupyter笔记本电脑（使用Python）将包括（i）用户友好的统计技术，可为选择“最佳拟合”模型选择，以及（ii）用于有效数据归档和用户“按需”绘图的新算法。宽度分布和TL-MC的使用是首要任务。资金将支持共享TL-MCS和培训用户的策略，这些策略包括对MCS网站，在线和个人研讨会以及用英语和西班牙语提供的在线教程的连续更新。由于TL-MCS具有复杂的功能，因此对高级用户的额外培训将专注于有效，有效的建模策略，并包括出版有效建模实践的路线图。将TL-MCS应用于全球火成岩地区，将使潜水员的研究人员能够探索这些系统的开放系统转换层的演变。为潜水员和博士后研究人员提供的资金将支持他们的科学和专业发展，并将他们定位为加入地球科学劳动力，以训练有素的计算机模型。机会将包括设计和执行研究项目和教程，撰写建议，在研讨会和教程开发中的领导角色，口头演示，同行评审的出版物以及专业网络的发展。最后，将通过在线世界范围内的开放系统岩浆流程工作组获得更多参与开放系统流程研究的机会，资金科学家将启动和管理。该项目由地理科学局与高级Cyber​​infrasture办公室的合作共同汇集，以支持AI/ML和开放的科学活动。基金会的智力优点和更广泛的影响审查标准。
