Pacific centre for isotopic and geochemical research

太平洋同位素和地球化学研究中心是一个致力于地球化学创新的主要分析设施，设在不列颠哥伦比亚大学地球和海洋科学系。该设施为来自加拿大和其他国家的大学、政府机构和采矿业的研究人员提供地球、环境、海洋、大气和生物科学研究需求。PCIGR的主要目标是(1)提供一个完全集成的分析设施，以促进地球、海洋和环境科学研究的新途径；(2)与其他学科，如医学、生物和化学科学建立富有成效的合作；(3)吸引和留住加拿大和国际科学界的研究人员；以及(4)提供高质量的分析服务。拟议的研究主题包括：全球气候研究、地幔和岩石圈中的地球化学示踪剂、海洋生物地球化学循环、古海洋学、环境地球化学、地质过程的时间尺度和速率以及地球中的金属。在PCIGR开展的广泛的地球化学研究是加拿大独有的，真正是多学科的，反映了PCIGR用户的专业知识和研究兴趣的范围。该设施的中心是安装在新洁净室的7台质谱仪、一系列元素和气体分析器、3个新的化学清洁实验室和一个无机地球化学实验室的分析能力。目前正在研究的同位素和化学系统包括示踪剂中的放射性同位素(Th-PA、铅-铅、Rb-锶、Sm-ND、Lu-Hf)和年代学研究(U-Pb、Ar-Ar)，地质和生物材料中的重稳定同位素(Fe、Mo、Cd、Mg、Cu、Zn、Li)，碳酸盐矿物、沉积物、水和气体中的轻稳定同位素(C、O、H、N)，以及地球、海洋和环境物质的微量元素特征。

The Pacific Centre for Isotopic and Geochemical Research (PCIGR) is a major analytical facility dedicated to innovation in geochemistry that is housed in the Department of Earth and Ocean Sciences (EOS) at the University of British Columbia. This facility serves the earth, environmental, oceanographic, atmospheric and biological science research needs of investigators from universities from across Canada and other countries, government agencies, and the mineral industry. The primary goals of the PCIGR are (1) to provide a fully integrated analytical facility to stimulate new avenues of research in the earth, ocean, and environmental sciences, (2) to establish productive collaborations with other disciplines, such as the medical, biological, and chemical sciences, (3) to attract and retain researchers from the Canadian and international scientific communities, and (4) to provide high-quality analytical services. The proposed research themes include: global climate studies, geochemical tracers in the Earth's mantle and lithosphere, marine biogeochemical cycles, paleoceanography, environmental geochemistry, timescales and rates of geologic processes, and metals in the Earth. The broad range of geochemical research that is carried out at the PCIGR is unique to Canada and truly multi-disciplinary, reflecting the range of expertise and research interests of the users of the PCIGR. The facility is centred around the analytical capabilities of 7 mass spectrometers housed in new clean rooms, an array of elemental and gas analyzers, 3 new chemical clean laboratories, and an inorganic geochemical laboratory. Isotopic and chemical systems currently under investigation include radiogenic isotopes in tracer (Th-Pa, Pb-Pb, Rb-Sr, Sm-Nd, Lu-Hf) and geochronological studies (U-Pb, Ar-Ar), heavy stable isotopes in geologic and biologic materials (Fe, Mo, Cd, Mg, Cu, Zn, Li), light stable isotopes (C, O, H, N) in carbonate minerals, sediments, waters, and gases, and trace element characterization of earth, ocean, and environmental materials.
