Re-Os同位素示踪与定年研究进展及发展趋势

Re-Os同位素是近年来发展起来的一门新兴的同位素地球化学方法,已广泛应用于金属矿床、壳—幔作用和有机质样品等的示踪和定年。本文综述了近年来对Re-Os同位素的研究成果,总结了Re-Os同位素分析测试技术、地质上的应用、测试样品种类等科学问题上的研究进展。在介绍各种分析方法和应用的优越性及其不足的基础上,提出了今后的发展方向,认为提高Re-Os同位素分析测试水平、拓展测试样品种类、与其它常规的同位素体系结合起来应用是Re-Os同位素体系今后的发展趋势。

Advances and Development in the Study of Re-Os Isotope Tracer and Dating Methods

Re-Os isotope study is developed in recent years as a new isotope geochemical method. It has been widely used in the tracing and dating of metal ore deposits, crust-mantle action and organic samples. Re-Os isotope research results in recent years are reviewed in this paper, summing up the research progress of scientific problems, such as Re-Os isotope analysis testing technology, geological application and varieties of test samples. On the basis of introduction on superiority and deficiency of each analysis methods and application, the development direction in the future was put forward, we think that improving the level of Re-Os isotope analysis testing, developing test sample types, combining with other conventional isotope system are the development trend of Re-Os isotope system in the future.
