Technician Support: Syracuse University Noble Gas Isotope Research Laboratory (SUNGIRL)

EAR-0130833Baldwin 此 NSF 奖项支持雪城大学稀有气体同位素研究实验室 (SUNGIRL) 的技术职位。 该职位目前由 Laura Webb 博士担任，费用由雪城大学的捐款分摊。 SUNGIRL 包括 1) 一台最先进的 Micromass 5400 惰性气体质谱仪和主要用于 40Ar/39Ar 分析的萃取线，以及 2) 一台四极杆质谱仪和自动萃取线，用于结合 (U-Th)/He 定年进行 He 分析。该实验室由地球科学领域的两名教员苏珊·鲍德温和保罗·菲茨杰拉德共用，他们的研究重点是地壳的热年代演化。该合同最初将允许实验室及时完成和调试，包括稀有气体提取线的自动化。在这个奖项的过程中，我们还计划建立一个激光系统，用于对厚截面中的矿物进行原位分析，以及结合 (U-Th)/He 和 40Ar/39Ar 热年代学对矿物颗粒进行脱气。该实验室将供雪城大学教职员工、研究人员、博士后研究员、研究生和本科生以及美国和国际访问研究人员使用。 在 PI 的总体指导下，Webb 博士将负责实验室的日常管理和运营，包括设备维护、设计修改和惰性气体质谱技术的开发。 Webb 博士还将参与正在进行的 NSF 资助的研究，其中包括大陆伸展区域（盆地省、横贯南极山脉）和斜辐合区域（新西兰南阿尔卑斯山）的热年代学分析（40Ar/39Ar、(U-Th)/He 和裂变径迹）。我们还与 Geoff Seltzer 及其同事合作，对秘鲁-玻利维亚高原的第四纪晚期火山灰进行了年代测定，以便利用 NSF 资助的研究获得的钻芯，为热带安第斯山脉的古气候研究提供地质年代学框架。 将利用 SUNGIRL 的待决 NSF 提案包括比利牛斯碰撞造山带和巴布亚新几内亚西部伍德拉克盆地活跃变质核心复合体的热年代学研究。

EAR-0130833BaldwinThis NSF award supports a technical position in Syracuse University's Noble Gas Isotope Research Laboratory (SUNGIRL). The position, currently filled by Dr. Laura Webb, is cost shared with contributions from Syracuse University. SUNGIRL consists of 1) a state-of-the-art Micromass 5400 noble gas mass spectrometer and extraction line used primarily for 40Ar/39Ar analyses, and 2) a quadrupole mass spectrometer and automated extraction line for He analysis in conjunction with (U-Th)/He dating. The laboratory is shared by two faculty members in Earth Sciences, Suzanne Baldwin and Paul Fitzgerald, whose research focuses on the thermochronologic evolution of crustal terranes. The award will initially allow timely completion and commissioning of the lab, including automation of the noble gas extraction line. During the course of this award we also plan to build a laser system for in situ analysis of minerals in thick sections, as well as outgassing of mineral grains in conjunction with (U-Th)/He and 40Ar/39Ar thermochronology. The laboratory will be utilized by Syracuse University faculty, researchers, post-doctoral fellows, graduate and undergraduate students, and visiting U.S. and international researchers. Under the general direction of the PIs, Dr. Webb will be responsible for the day-to-day management and operation of the laboratory including maintenance of equipment, design modifications, and development of noble gas mass spectrometric techniques. Dr. Webb will also participate in ongoing NSF-sponsored research which presently includes thermochronologic analyses (40Ar/39Ar, (U-Th)/He, and fission track) in areas of continental extension (Basin and Range Province, Transantarctic Mountains) and oblique convergence (Southern Alps of New Zealand). We are also dating late Quaternary volcanic ashes from the Peruvian-Bolivian Altiplano in collaboration with Geoff Seltzer and colleagues in order to provide a geochronological framework for paleoclimatic research of the tropical Andes utilizing drill cores obtained through NSF funded research. Pending NSF proposals that will utilize SUNGIRL include thermochronologic research in the Pyrenean collisional orogen and in the active metamorphic core complexes of the Western Woodlark Basin of Papua New Guinea.
