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.

Baldwin-0130833该NSF奖项支持锡拉丘兹大学稀有气体同位素研究实验室（SUNGIRL）的技术职位。 该职位目前由劳拉·韦伯博士担任，费用由锡拉丘兹大学分担。 SUNGIRL由1）最先进的Micromass 5400惰性气体质谱仪和主要用于40 Ar/39 Ar分析的提取线，以及2）四极质谱仪和用于He分析的自动提取线以及（U-Th）/He定年。该实验室由地球科学的两名教师Suzanne Baldwin和Paul Fitzgerald共享，他们的研究重点是地壳岩石的热年代学演化。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。在此期间，我们还计划建立一个激光系统，用于厚切片中矿物的原位分析，以及与（U-Th）/He和40 Ar/39 Ar热年代学相结合的矿物颗粒的放气。该实验室将由锡拉丘兹大学的教师，研究人员，博士后研究员，研究生和本科生，以及访问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NSF赞助的正在进行的研究，目前包括大陆伸展（盆岭省，横贯南极山脉）和斜向会聚（新西兰南阿尔卑斯山）地区的热年代学分析（40 Ar/39 Ar，（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测年，以便利用NSF资助的研究获得的岩心，为热带安第斯山脉的古气候研究提供地质年代学框架。 美国国家科学基金会提出的利用SUNGIRL的建议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动变质核杂岩中进行热年代学研究。
