| 摘 要： | “中央造山带”的提法响亮，瞩目，但其真正含义应加以分析，思考，从地理山脉综合分析表明它们不是统一山脉，但现实却出现一带山系，横贯中国大陆中央，故地理上可知经而统之称其为一道“中央山系”地质含义分析证明它们不是统一造山带，但祁连，昆仑，秦岭和大别可为广义统一造山带，有东古特提斯和中国大陆完成其主体最后拼合的关键地带之一，研究“中央造山系”有以下几个关键问题；（１）新生代，尤其是新第三纪以来中央造山带

| Abstract: | The term Central Orogenic System has been recently coined and is immediately accepted in the geological circles of China. The true connotation of this new term, however, needs further considerations. From the geographic point of view, the mountains comprising this system are markedly arrayed from east to west into a high mountain chain across the middle part of China continent, and thus can be reasonably called central mountain system, including the Dabieshan, the Qinling, Qilian, and Kunlun mountains. These moutain ranges are now geologically treated as individual orogens, but recent studies demonstrate that they are actually, in a broad sense, parts of a huge orogenic zone where the Eastern Paleo_Tethyan ocean was closed and consequently the adjacent blocks and terranes were integrated. Some of the key problems are addressed in this paper concerning the Central Orogenic System. (1)Did the Central Orogenic System suffer the dismemberment into several segments along its strike during the Cenozoic, in particular since the Neogene? And did the dismembering exert a strong impact upon natural environments or cause any natural calamities in adjacent regions? (2) Did the individual orogen within the system develop under a similar tectonic regime? (3) What is the relationship between the Paleo_Tethys and the Central Orogenic System? (4) What is the nature of early Paleozoic plate_tectonics of the Central Orogenic System? And what is the tectonic background of the Neoproterozoic Central Orogenic System? (5) What are the similarities and uniqueness of the individual orogens within the system? And what is their tectonic significance? The Central Orogenic System therefore should be studied in the light of continental dynamics and based upon a multidisciplinary approaches. The research outcome will surely provide insights into the detailed processes of the continental deformation and further promote the development of earth sciences in China. |
