Symposium on Tephrochronology and Hominid Evolution in East Africa to be held in Yellowstone National Park, June 1990

国际第四纪协会大会间年代学委员会将于1990年6月在怀俄明州举行实地会议和讲习班。这是为了促进国际交流，确定世界研究的现状，评估相关领域的新发展的影响，并促进就火山喷发在解决第四纪基本地层问题中的作用进行对话。这项奖励是为了支付一个关于这些测年机制与东非原始人化石问题的关系的研讨会的费用。与人类起源有关的一些最令人兴奋的发现来自东非，化石地层对比是确定各种早期原始人化石年代的最重要机制之一。研讨会的所有与会者都为古人类学知识的发展做出了或正在做出重大贡献。

The Inter-Congress Committee on Tephrochronology of the International Quaternary Association will hold a field conference and workshop in Wyoming in June, 1990. This is to promote international communication, determine current status of worldwide studies, assess the impact of new developments in related fields, and promote dialogue on the role of tephra (volcanic extrusions) in solving fundamental Quaternary stratigraphic problems. This award is to defray expenses for a symposium on the relationship of these dating mechanisms to questions of hominid fossils in East Africa. Some of the most exciting finds relating to human origins have come from East Africa and tephrostratigraphic correlations have been among the most important mechanisms to fix firmly the dates of various early hominid fossils. All the participants in the symposium have made, or are making, substantial contributions to the advancement of paleoanthropological knowledge.
