9316951 Mattinson This award provides one-half the funding needed to modernize a thermal ionization source mass spectrometer operated in the Department of Geological Sciences at the University of California at Santa Barbara. The institution is committed to providing the remaining funds necessary for the project. The research projects necessitating the upgrade include geochronology of very small samples using uranium-lead isotopes, tracer studies of mantle processes, and uranium disequilibrium dating studies of marine carbonate materials. The upgrades to the instrument will enhance its ability to analyze very small amounts of samples, a basic requirement of the research. ***

9316951 Mattinson该奖项提供了一半的资金需要现代化的热电离源质谱仪在地质科学系在加州大学圣巴巴拉。该机构承诺提供该项目所需的其余资金。需要升级的研究项目包括使用铀-铅同位素对极小样品进行地质年代学研究、地幔过程的示踪剂研究以及海洋碳酸盐物质的铀不平衡测年研究。仪器的升级将提高其分析极少量样品的能力，这是研究的基本要求。***
