摘要
国际变质作用与地壳演化学术讨论会在长春召开,历时4天。会议期间,代表们就变质地质学的各方面课题广泛交流了研究成果和观点;讨论涉及变质图的编图原则和方法及变质作用类型与大地构造环境之间的关系;对前寒武纪变质地质和蓝片岩相变质作用的特征及大地构造环境进行了较集中的讨论。与会代表最感兴趣的问题是各时代造山带长期复杂的变质和变形作用的演化历史及彼此之间的复杂时间关系。对花岗质岩石学及与变质岩系有关的金和铀的成矿作用也引起了注意。
The International Symposium on Metamorphism and Grustal Evolution proposed and sponsored by Changchun University of Earth Sciences was held in 20-23 September, 1988 in its campus.And after the meeting, part of the participants went on an excursion to Miyun district in a Beijing suburb in 21-27 September,145 representatives attented to this meeting. They come from Australia, India, Italy, Japan, Netherland, West Germany, U . S. A .and China, 42 papers were delivered at the meeting.In scientific sessions, representatives extensively exchanged their results of research and ideas on various subjects of metamorphic geology. The principles and method for compllating metamorphic map and relationships between metamorphic type and tectonic setting were firstly concerned. Many discussions were focused on the Precambrianmetamorphic geology and characteristics and tectonic environment of blueschist-facies metamorphirm. The specular complex evolutional hsitory of metamorphie events and tectonic deformation aeec mpanied intricate temporal rela-tionshipbeiween them in most orogenic belts of various age was the most interesting subject to all participants. Some attentions also were paid to petrology of granitic eocks and metallogene of gold and urarium related to metamorphic rock series. The meeting is successful and was greatly appreciated by the representatives. And it will certainly contribute to farther progress in field of metamorphic geology.
