Analytical facilities for dating geological materials are important for education, research and economic and petroleum geology exploration. The AGES (Argon Geochronology for Earth Sciences) laboratory at Lamont-Doherty Earth Observatory was established in 1997, and actively contributes to all of these goals working with both academic and industry colleagues. This award will provide funding to acquire a new-generation noble gas mass spectrometer and pumps for its extraction line to set up a state-of-the art instrument for high precision measurements of Argon isotopes that permit dating of geological materials. This improved capability provides extraordinary opportunities for improving our understanding of Earth's history of climate variability, biological evolution and mountain-building processes. The training of students in analytical procedures and geochronology methods will be greatly enhanced by access to state-of-the-art instrumentation. Over the past several years, the advent of a new generation of noble gas mass spectrometers for Ar-Ar dating is greatly improving the precision with which small samples can be analyzed. Such improvements are critical for the goal of sequencing Earth History with a seamlessly integrated Ar-Ar : U-Pb : astrochronology time-scale and for probing important events in Earth's history such as extinctions, dramatic climate changes and evolutionary pathways. This funding will allow the purchase of a state-of-the-art noble gas instrument as well as peripheral parts for building an extraction line for introducing samples to the instrument. The AGES lab at LDEO has been an active participant in EARTHTIME activities that are dedicated towards the goal of accurately sequencing Earth history. The upgrade that will come from the acquisition of this new generation of instrument will transform the ability to continue to be actively involved in EARTHTIME while also continuing to train students and post docs and serve a large collaborative user base.

约会地质材料的分析设施对于教育，研究，经济和石油地质探索很重要。 Lamont-Doherty Earth天文台的年龄（地球科学的年代）实验室成立，并于1997年成立，并积极地为与学术和行业同事一起工作的所有这些目标做出了贡献。该奖项将提供资金，以获取新的贵族气体质谱仪和泵的提取线，以建立最先进的工具，以高精度测量氩同位素的高精度测量，以允许地质材料的约会。这种提高的能力为提高了我们对地球气候变异性，生物进化和山区建设过程的理解提供了非凡的机会。通过获得最先进的仪器，将大大增强学生对分析程序和地质学方法的培训。在过去的几年中，新一代贵族气体质谱仪的出现大大提高了可以分析小样本的精确度。这样的改进对于通过无缝整合的AR-AR进行测序的目标至关重要。这笔资金将允许购买最先进的贵重燃气仪器以及外围零件，用于构建提取线，以将样品引入乐器。 LDEO的年龄实验室一直是地球活动活动的积极参与者，该活动致力于准确测序地球历史。从收购新一代工具的升级将改变继续积极参与地球时间的能力，同时还继续培训学生并发布文档并为大型协作用户群服务。
