Understanding the evolution of the Earth relies heavily on our ability to read, understand and interpret chemical and physical evidence archived in terrestrial material, such as the rock record and organic materials. One cornerstone for almost all research projects focusing on better understanding major geologic events are chemical analyses of rock samples and minerals, as their geochemical inventory can be used to reconstruct processes at different scales, such as ore-genesis, continental-scale events like the eruption of Columbia River Flood Basalts that shaped the landscape of the Pacific Northwest, or how some of the Earth’s earliest crust has formed. This funding will be used to acquire a state-of-the-art laser-ablation Inductively Coupled Plasma Mass Spectrometry system, replacing our current instruments at the Peter Hooper GeoAnalytical Laboratory at Washington State University (WSU) founded more than four decades ago. The Lab specializes in providing research-quality geochemical data to the national (and international) earth-science community, many projects of which are funded by the NSF. This data is used to advance our understanding of Earth’s history. To continue to fulfill our mission in the future, we need to replace our current instruments that have been in year-round operation for more than a decade, and which are no longer supported by the manufacturer. The latest generation of mass spectrometer allows for the quantification of much lower concentrations of trace elements in whole rock samples and permits the development of new approaches for reading and interpreting geochemical signatures in earth materials. The laser ablation system coupled to the mass spectrometer allows for in-situ analysis at a micrometer-scale in minerals and an almost unlimited range of materials, allowing for use of the Lab by researchers from a wide range of disciplines, such as the earth sciences, material sciences, and biological sciences. The new instrument will be central for faculty and student research at WSU, and for the Lab’s other users. With this state-of-the-art equipment we will be able to develop new analytical approaches and methods, furthering our ability to tackle long-standing questions about Earth’s history on multiple scales. Students will be trained on cutting edge analytical instruments and, therefore, this award will also directly positively impact the highly trained workforce in the field of analytical geochemistry and beyond. The Peter Hooper GeoAnalytical Laboratory at Washington State University (WSU) has analyzed 12,200 bulk samples via solution Inductively coupled plasma mass spectrometry (ICPMS) over the last 5 years (2016-2021), plus more than 2000 hours of Laser Ablation (LA)ICPMS analyses in the last 3 years alone. This proposal requests funds to acquire a new state-of-the-art ICPMS and LA system for continuing and expanding the high quality and reliable services of trace element analyses for the geoscience community for the next decade and beyond. (LA)ICPMS analyses, especially in combination with XRF measurements, are employed in a broad range of Earth science research including applications in geological and environmental studies. Quantifying the composition of Earth materials, which include igneous, metamorphic, and sedimentary rocks, soils, and archeological artifacts, to name only a few, provides critical information about the samples’ origins and what processes were involved in their formation. Our analytical service employing (LA)ICPMS supplies high-quality research data to a wide range of geoscientists in North America - over 100 different institutions over the last 3 years have benefited from our services. The GeoAnalytical Lab is considered a critical component of academic geoscience research in North America through the research-quality analytical services it provides, most notably but not exclusively for the geochemical research communities. Data produced by the Lab feeds basic research which informs decisions made by scientists and agencies addressing natural hazards, resource exploration, environmental challenges, and human impacts on climate. The GeoAnalytical Lab also plays an important role in training highly skilled geochemists and technicians for the national workforce in the private and public sectors. These skills can only be acquired in an active research environment. The WSU GeoAnalytical Lab contributes to this educational mission in four ways: (1) through formal course instruction and hands-on training of WSU graduate students from a variety of disciplines, (2) through undergraduate research projects that use the instrumentation, (3) through training of visiting students, and (4) through employment of part-time student labor, which introduces students to the skills and responsibility required to successfully perform laboratory procedures.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.

了解地球的演变在很大程度上取决于我们在陆地材料（例如岩石记录和有机材料）中读取，理解和解释化学和物理证据的能力。几乎所有研究项目的一个基石都集中在更好地理解主要地质事件上是对岩石样品和矿物的化学分析，因为它们的地球化学清单可用于在不同尺度上重建过程，例如矿石生成，例如哥伦比亚河爆发，例如北部北部的境地，或者构成了北部地区的境地，或者构成了北部地区的洞察力，或者造成了一些earl虫。这笔资金将用于获取最先进的激光燃料电感耦合等离子体质谱系统，从而在华盛顿州立大学（WSU）的Peter Hooper Geoanalyalication实验室取代了我们目前的乐器，该乐器成立了四十多年前。该实验室专门为国家（和国际）地球科学界提供研究质量的地球化学数据，其中许多项目由NSF资助。这些数据用于促进我们对地球历史的理解。为了继续在将来履行我们的任务，我们需要替换已经全年运营已有十多年的当前工具，并且不再得到制造商的支持。最新一代的质谱仪可以量化整个岩石样品中较低浓度的微量元素，并允许开发用于读取和解释地球材料中地球化学特征的新方法。耦合到质谱仪的激光消融系统可以在矿物质和几乎无限的材料范围内进行原位分析，从而允许来自广泛学科的研究人员（例如地球科学，材料科学和生物学科学）的研究人员使用实验室。新仪器将是WSU的教师和学生研究以及实验室其他用户的中心。借助这种最先进的设备，我们将能够开发新的分析方法和方法，从而进一步解决有关在多个尺度上解决地球历史的长期问题的能力。学生将接受尖端分析工具的培训，因此，该奖项还将直接影响分析地球化学及其他领域训练有素的劳动力。华盛顿州立大学（WSU）的彼得·胡珀（Peter Hooper）地理分析实验室通过溶液通过溶液在过去5年（2016-2021）（2016-2021）中分析了1200个散装样品，并在过去的5年中分析了激光（Laser Gunation）（Laser Enblation Enblation（Laser Gunation）（Laser Enblation Enblation（Laser）超过2000小时）单独使用的超过2000小时的ICPMS分析。该提案要求资金购买新的最先进的ICPMS和LA系统，以延续和扩大未来十年及以后的地球科学社区的痕量元素分析的高质量和可靠服务。 （LA）ICPMS分析，尤其是与XRF测量相结合的分析，用于广泛的地球科学研究，包括在地质和环境研究中的应用。量化地球材料的组成，包括火成岩，变质和沉积岩石，土壤和考古文物，仅举几例，提供了有关样品起源以及其编队中涉及哪些过程的关键信息。我们采用（LA）ICPMS的分析服务向北美广泛的地球科学家提供了高质量的研究数据 - 在过去的3年中，超过100个不同的机构从我们的服务中受益。通过它提供的研究质量分析服务，地球分析实验室被认为是北美学术地球科学研究的关键组成部分，最值得注意的是，但不是仅针对地球化学研究社区。实验室产生的数据为基础研究提供了依据，该研究为科学家和机构做出的决策提供了解决自然危害，资源探索，环境挑战以及人类对气候的影响的决定。地理分析实验室在培训高技能的地球化学主义者和技术人员为私营部门和公共部门的国家劳动力方面发挥着重要作用。这些技能只能在积极的研究环境中获得。 WSU地球分析实验室以四种方式为这项教育任务做出了贡献：（1）通过正式的课程指导和对WSU的研究生的动手培训，（2）通过使用仪器的本科研究项目（3）通过培训访问学生的培训以及（4）通过培训培训和授予学生劳动的责任，以实现培训，以实现培训，以实现授权的责任，这些授权的责任，这些劳动的责任，这些劳动的责任，这些劳动的责任，这些劳动的责任，这些劳动力的责任，这些劳动律师的责任，这些劳动绩效的责任，法定使命，并使用基金会的知识分子优点和更广泛的影响标准通过评估被认为是宝贵的支持。
