International Research Fellow Awards: Stable Isotope Character of Transition Metal Carbonates, Australia

9901157梅尔基奥尔国际研究员奖励计划使美国科学家和工程师能够在国外进行3到24个月的研究。该计划的奖项提供了联合研究的机会，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将支持梅诺明民族学院的Erik B.Melchiorre博士与澳大利亚新南威尔士州西悉尼尼皮安大学的Peter A.Williams博士进行为期四个月的博士后研究访问。这项研究将涉及过渡金属碳酸盐的基础同位素研究，以确定其形成的各个方面。梅尔基奥尔博士将组装和分析孔雀石、天青石和其他过渡金属碳酸盐样品。实验确定的分馏系数将用于解释天然样品的形成条件。澳大利亚国家博物馆距离现场不远，提供了大量二价阳离子碳酸盐的收藏，包括许多来自目前无法进入的矿山的历史样品。除此之外，还有机会对自然产生的二价阳离子碳酸盐进行实地研究，这是澳大利亚深度风化的结果。

9901157MelchiorreThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twentyfour months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide support for a four-month postdoctoral research visit by Dr. Erik B. Melchiorre of the College of the Menominee Nation to work with Dr. Peter A. Williams at the University of Western Sydney Nepean in New South Wales, Australia.This research will involve basic isotope studies of transition metal carbonates to define aspects of their formation. Dr. Melchiorre will assemble and analyze malachite, azurite and other transition metal carbonate samples. Experimentally determined fractionation factors will be used to interpret the conditions of formation of natural samples.The Australian National Museum is within a short drive from the site, providing access to an extensive collection of divalent cation carbonates, including many historical samples from mines that are presently inaccessible. Added to this is the opportunity to do field work on naturally occurring divalent cation carbonates, which are a result of Australia's deep weathering.***
