中文摘要: 纪念老一代地球科学家李四光先生,思考地球科学与大地构造学的创新发展。文章以秦岭造山带为例思考大陆复合造山及其动力学,认知概括秦岭造山带基本属性与特质,探索认识中小多板块多期洋陆俯冲造山-陆-陆板块俯冲碰撞造山的板块复合造山,并又强烈叠加复合陆内造山,造成复杂组成与结构,形成立交桥式四维流变学分层的多层非耦合动态演化的大陆复合造山带模型,及其新的演化趋势动态和构成国家人类需求的成矿成藏物质财富与宜居的地表系统环境等,期望前瞻探索认知地球发展的未来。文章还就秦岭造山带几个有争议的问题,进行简要讨论,共求新的探索研究发展。期盼学习李四光先生学术理论精华,尤其在深化发展板块构造,探索认知大陆构造与动力学方面,创新发展地质力学,以宇宙太阳系视野探索地球动力学,推动大地构造新发展。
Abstract:To cherish the memory of geological pioneer J.S.Lee and think about the innovation development of Earth science and tectonic theory, the composite orogeny and dynamics of the Qinling orogen, based on further understanding of the fundamental characteristics of the Qinling orogen, is reconsidered. The Qinling orogen has so far experienced middle-small sized plates, multi-episode ocean-continent subduction, continent-continent collision and intracontinental orogeny, and eventually formed complex component and structure, and the continental composite orogen model of 4-D "overpass-type", rheological stratification, decoupling structure in dynamic evolution. As a result, the habitable Earth surface system and abundant natural resources serving the human society development and national needs have been created. Some issues on controversy are also briefly discussed for reconciling the insights on the Qinling orogen and deepening the study of continental composite orogen, and expecting to grasp J.S.Lee's academic essence for exploring continental tectonics and dynamics, developing plate tectonics theory and Geomechanics, studying Earth dynamics in the vision of the Solar system and universe and pushing the tectonic theory forward.
