项目摘要

NSF/MRI funds will be used to purchase a new generation multi-collector thermal ionization mass spectrometer. The new instrument, which will replace a 20 year old instrument, will be used for high precision U-Pb geochronology, and Nd, Sr, Pb, Li isotope tracer studies in tectonic, petrologic, sedimentologic, hydrologic, and paleoclimatologic research at Syracuse University and the State University of New York at Oswego. Broader Significance and ImportanceIt is difficult to overemphasize the importance of determining the isotopic composition of Earth materials to virtually all fields within the geosciences. For instance, our ability to determine precise ages of rocks has continued to increase with every new generation of scientific instrument. A geologic event that occurred over 100 million years ago can now be determined to within 0.1 million years. This ability allows us to investigate critical events in Earth history, such as testing the hypothesis that massive volcanic eruptions coincided with mass extinctions, assessing if climate change occurred in response to major mountain building events, and to correlate oil-bearing sedimentary strata over significant distances. The acquisition of a new generation mass spectrometer gives us an unprecedented ability to determine the timing of major geological events and thus understand better over four billion years of Earth history. The new instrument will also be extensively used to train the next generation of Earth scientists to collect the geochemical data needed to address issues of energy resources, climate change, natural hazards, and water resources.

NSF/MRI基金将用于购买新一代的多核心热电离质谱仪。该新仪器将取代20年历史的仪器，用于高精度U-PB地质学，以及ND，SR，PB，LI同位素示踪剂研究，用于锡拉丘兹大学和纽约州立大学奥斯特沃戈大学的构造，质学，沉积学，水文和古质性研究。更广泛的意义和重要性很难过分强调确定地球材料对地球科学中几乎所有领域的同位素组成的重要性。例如，我们确定岩石精确年龄的能力随着新一代的科学仪器的发展而继续增加。超过1亿年前发生的地质事件现在可以确定在110万年之内。这种能力使我们能够调查地球历史上的关键事件，例如测试以下假设：大规模火山喷发与大规模灭绝一致，评估气候变化是否响应重大的山区建筑事件而发生，并将含油的沉积地层相关联。新一代质谱仪的获取使我们具有确定重大地质事件时机的前所未有的能力，因此在地球历史上更好地理解了超过40亿年的地球历史。新工具还将广泛用于训练下一代地球科学家，以收集解决能源资源，气候变化，自然危害和水资源问题所需的地球化学数据。
