本文就宁鎮山脈西段地区中生界侏罗系象山羣的构造和浙西加里东地槽海西构造的分析,論述地貭构造形成和发展的二种相对形式——继承和上迭,进一步証实上述二区爭論已久的印支褶縐运动和加里东褶縐运动的存在。同时指出,地槽內继承和上迭构造相对出現,不仅标誌着褶縐运动的存在,而且客观地反映了褶縐运动的空間分布和时間持續的差異性。从而产生了上迭构造和继承构造二种表現形式。作者等认为二者不是截然对立,而是相对地同时并存於地槽褶縐結束的統一发展图案中。
This paper analyzes the structure of the Jurassic Xiangshan Group in the Mesozoic Jurassic and the Hercynian structure in eastern Zhejiang in the western section of the Ningzhen Mountains and discusses the two relative forms of the formation and development of the mesopena - Further confirms the existence of the controversial Indo-China Crepuscular and Caledonian Crepe movements of the two districts mentioned above. At the same time, it is pointed out that the relative succession and succession structure in the trough not only indicate the existence of pleat movement, but also objectively reflect the spatial distribution and time difference of pleat movement. As a result, two manifestations of the structure of Diego and the structure of succession emerged. The author believes that the two are not diametrically opposite, but relatively simultaneously co-exist in the unified development pattern of the end of the trench crepe.
