“大陆构造及成矿作用研究现状”笔谈会

DISCUSSION ON CONTINENTAL STRUCTURE AND METALLOGENESIS BY WRITING

在探索地球岩石圈构造及其演化中,人们认识到必须把注意力集中于大陆构造.因为现代海洋年龄仅两亿年,大陆岩石圈则全面系统地保留了四十六亿年来岩石圈的变形构造和演化过程,所以大陆及其边缘被列为80年代国际岩石圈计划的主要研究课题.我国夹持在西伯利亚板块、印度板块和太平洋板块之间.在几大板块的相互作用中,中国大陆展现了一幅丰富多彩、复杂纷繁的构造图景.为了探索我国东部大陆构造及其形成演化的规律,开拓找矿远景,今秋将在中国地质大学(武汉)召开“中国东部大陆构造及成矿作用讨论会”.本刊约请几位专家对大陆构造中的几个问题抒发己见,供关心大陆构造及成矿作用研究现状的同志们参考.今后我们还将采用这种笔谈形式对地质领域的重大课题进行讨论交流.

In order to pursue the generating and evoluing regularity of conti-nental structure in East China and widen the exploring prospect, editors have organized a discussion by writing on the subject about the present research state of continental structure and metallogenesis. Several geological specialists were invited to express their views and opinions to those who are interested in the study of continental structure and metallogenesis for reference. The main topics are the study of strike-slip faults in oil and gas basin in China; the structure evolution of metamorphic core complex in Qin-ling orogenic belt and the continental lithosphere construction of East Qin-ling, the special feature of research on continental margin structure in China, the study of continental orogen belts in China; the structure investigation of continental basin, the continental block structure and rotation, and the research on continental margin surrounding the Pacific ocean.
