Support of International Participation in the Geochemical Society Symposium on Global Isotope Stratigraphy

本次会议涉及一个名为“古生代和中生代早期海洋沉积物中的氧和碳同位素：走向全球同位素地层学”的地球化学学会研讨会，该研讨会将于1990年10月30日星期二与美国国家地理学会在达拉斯举行的会议一起召开。本次研讨会直接讨论了美国国家科学基金会全球变化地质记录项目的目标。全球同位素地层学的发展和理解需要良好的地理覆盖，以将区域信号与全球信号区分开来。这反过来又需要国际社会的参与。此外，由于区分改变和未改变标本所涉及的定性技术，在样品和数据交换方面的国际合作至关重要。

This conference concerns a Geochemical Society Symposium entitled: "Oxygen and carbon isotopes in Paleozoic and Early Mesozoic marine sediments: toward a global isotope stratigraphy", to be convened Tuesday, October 30, 1990 in conjunction with the National Geographic Society of American meeting in Dallas. This symposium directly addresses the goals of the NSF program on the Geologic Record of Global Change. The development and understanding of a global isotope stratigraphy requires good geographic coverage to separate the regional from the global signal. This in turn requires international involvement. Furthermore, because of the qualitative techniques involved in distinguishing altered from unaltered specimens, international cooperation in sample and data exchange is vital.
