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。
International Metamorphism and Crustal Evolution Symposium held in Changchun, which lasted 4 days. During the conference, delegates extensively exchanged research results and opinions on various topics of metamorphic geology; discussed principles and methods of compilation of metamorphic maps and the relationship between metamorphic types and tectonic setting; Geology and blue lithofacies facies metamorphism and tectonic setting of the environment focused on the discussion. The most interesting issue for participants was the evolutionary history of the long-term and complicated metamorphic and deformational effects of the orogenic belts and their complicated time relationships. Attempts have also been taken to granite petrology and to the mineralization of gold and uranium associated with metamorphic rocks.
