Acquisition of Multicollector Inductively Coupled Plasma Mass Spectrometer for the Use in Geosciences

9976676 Ruiz该合同提供部分资金，用于购买由亚利桑那大学地质科学系安装和操作的多收集器电感耦合等离子质谱仪(MC-ICP-MS)。亚利桑那大学致力于提供收购所需的剩余资金。亚利桑那大学需要MC-ICPMS能力的研究应用包括：(1)从Os和Pb同位素分析会聚板块边缘的金属矿床的成因，(2)来自Fe、Cu和Zn同位素的极端环境中的生命，(3)通过对长石的原位锶分析来确定硅质岩浆室的起源，(4)利用Hf同位素研究地壳和地幔的演化史，(5)利用锆石中的原位U-Pb对会聚板块边缘进行年代学研究。(6)碳酸盐土壤的U-Th定年和利用洞穴和珊瑚的U-Th定年标定C-14时间标尺。

9976676Ruiz This award provides partial funding for the acquisition of a multicollector inductively-coupled plasma mass spectrometer (MC-ICP-MS) to be installed and operated by the Department of Geological Sciences at the University of Arizona. The University of Arizona is committed to providing the remaining funds necessary for the acquisition. Research applications at the University of Arizona requiring the capabilities of the MC-ICP-MS include (1) Origin of metal deposits at convergent plate margins from Os and Pb isotope analysis, (2) Life in extreme environments from Fe, Cu, and Zn isotopes, (3) Origin of silicic magma chambers from in situ Sr analysis of feldspars, (4) History of crust and mantle evolution using Hf isotopes, (5) Geochronology of convergent plate margins using in-situ U-Pb in zircons, and (6) U-Th dating of carbonate soils and calibration of the C-14 time scale by U-Th dating of speleothems and corals.***
