美国地球动力学委员会于3月在奥斯汀举行了一次专题讨论会,就岩石圈的一些学术争论问题进行了讨论。人们期望这样一次讨论会能为将来研究一些最有潜力的领域提供借鉴(正在撰写一份报告将发表在《科学》杂志上)。奥斯汀会议集中讨论了人们对全球大地构造的现有认识的性质:我们已经作过哪些假设?这些假设的正确程度如何?全球大地构造的主要问题是什么?面对不断出现的、不符合传统板块构造模式的大量资料应该怎么处理?按照新的资料应该对这个模式作哪些改进等。讨论岩石圈的障碍之一,就是它 The US Geodynamics Commission held a symposium in Austin in March to discuss some of the academic issues in the lithosphere. It is expected that such a seminar will serve as a reference for some of the most promising areas to be studied in the future (a report is being prepared to be published in Science). The Austin conference focused on the nature of what people know about the global geotectonics: what assumptions have we made? What is the correctness of these assumptions? What are the major problems with the global geotectonics? Faced with emerging, non-traditional segments How to deal with a large amount of information on the construction mode? According to the new information should be made on this model, such as improvements. It is one of the obstacles to discuss the lithosphere
