【摘要】 由于太平洋板块对欧亚板块的俯冲作用,中国东部经受了强烈的拉张作用力,在大兴安岭—太行山—长江三峡以东地区形成一系列中新生代断陷—坳陷盆地系统。渤海湾盆地、江汉盆地、苏北—南黄海盆地和北部湾盆地经历了两次以上的断陷—坳陷期。松辽盆地和南阳—泌阳盆地只有单旋回的断—坳期。盆地形成机解释为由于地壳拉张减薄引起上地幔的隆升。沿海大陆架为另一断陷—坳陷系统,东海盆地和台湾盆地属于西太平洋沟—弧—盆系统的边缘盆地。珠江口盆地和莺歌海盆地位于南海扩张板块的北部拉张边缘。更多还原

【Abstract】 Under the strong subduction of pacific plate with the Eurasian Plate,the Eastern China platform suffered strong regional tensional stresses.Mesozoic-Cenozoic Rift-subsi- ded Basins zone is located in the east of Daxinganling-Taihangshan-Yangtze Gorge.So- me Basins such as Bohai Gulf Basin,Jianghan Basin,Subei and Southern Yellow Sea Basin and Beibu Gulf Basin took their shapes after more than two stages of rifting and subsidence.Another basins such as Songliao Basin,and Nanyang-Biyang Basins were dominated only by one cycle rifting-subsiding stage.They can be explained by the crustal extention resulting from uplifting of the “Moho” and the solid rocks of the upp- er mantle. Another depression zone is located in the continental shelf of China.The East China Sea Basin and Taiwan Basin are the marginal basins of the Western Pacific trench-arc-ba- sin system.The Pearl River Mouth Basin and Yingge Sea Basin are located along the north divergent margins of South China Sea spreading plates.更多还原
