| 摘 要： | 从大陆岩石圈动力学角度 ,提出了江苏基础地质科学研究所面临的主要前沿问题 ,如 :造山带、超高压变质带、花岗岩侵入机制、大面积分布的中生代火山岩的形成等。并对此作了总体上的分析 ,提出了个人见解。认为从中生代开始 ,不能不考虑古太平洋板块的巨大作用和影响。在考虑大陆地壳动力学时 ,必须考虑大洋地壳运动学 ;考虑大陆地壳增生时 ,同时要考虑洋壳的增生及消亡 ;考虑陆壳和洋壳动力时离不开岩石圈下面软流层的动力学

| Abstract: | The authors put forward some main problems in terms of the basic geological research in Jiangsu such as orogenic belt, ultra high pressure metamorphic belt, intrustive mechanism of granite and formation of Mesozoic volcanic rocks distributed widely in a large scale. Through comprehensive analysis, the authors consider that it has become a very important factor to the effect and process of the Pacific Plate since Mesozoic age. It is an essential consideration for the importance of oceanic crust dynamics and its accretion or consumption during the study of continental crust dynamics and accretion or consumption. The dynamics research of continental and oceanic crusts should relate closely with the dynamics of rheosphere under the lithsphere. |
