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

美国国家科学基金会授予锡拉丘兹大学惰性气体同位素研究实验室（SUNGIRL）一个技术职位。该职位目前由劳拉·韦伯（Laura Webb）博士担任，费用由锡拉丘兹大学（Syracuse University）分担。SUNGIRL包括：1)最先进的Micromass 5400稀有气体质谱仪和萃取线，主要用于40Ar/39Ar分析；2)四极杆质谱仪和自动萃取线，用于He分析，并结合(U-Th)/He测年。该实验室由地球科学系的两名教员苏珊娜·鲍德温和保罗·菲茨杰拉德共同使用，他们的研究重点是地壳地体的热年代学演化。该合同最初将允许及时完成和调试实验室，包括惰性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，用于厚层矿物的原位分析，以及与(U-Th)/He和40Ar/39Ar热年代学相结合的矿物颗粒脱气。该实验室将由雪城大学的教职员工、研究人员、博士后、研究生和本科生以及来访的美国和国际研究人员使用。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，目前包括在大陆延伸（盆地和山脉省，横贯南极山脉）和斜辐合（新西兰南阿尔卑斯山）地区的热年代学分析（40Ar/39Ar, (U-Th)/He和裂变轨迹）。我们还与Geoff Seltzer及其同事合作，对来自秘鲁-玻利维亚高原的晚第四纪火山灰进行测年，以便为热带安第斯山脉的古气候研究提供一个地质年代框架，利用由美国国家科学基金会资助的研究获得的钻孔岩芯。NSF将利用SUNGIRL的未决提案包括在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的活跃变质岩心复合体中的热年代学研究。

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.
