摘要
大别造山带东南缘中新生代盆地是一个多成因的叠合盆地,不同学者对其在不同演化阶段的成因特征和形成机制认识有较大差异。根据构造演化、盆地成因和性质、沉积特征、成盆时的应力状态和地球动力学过程等特点划分出大别造山带东南缘中新生代沉积盆地四种类型,提出了盆地的形成与演化经历了中晚三叠世前陆盆地,早中侏罗世坳陷盆地、晚侏罗世-早白垩世早期火山喷发-沉积盆地、早白垩世中期—古近纪裂陷盆地和新近纪的坳陷盆地共5个阶段的新观点,统一了对大别造山带东南缘中新生代盆地成因类型及其形成机制的认识,对深化盆地性质认识、正确评估盆地资源有重要意义。
Southeastern margin of the Dabie Mountains is a multi-Cenozoic basin causes basin, different scholars at different evolutionary stages of its genesis and the formation mechanism of a greater understanding of differences. According to evolution, the causes and nature of the basin, sedimentary characteristics, into a basin, the stress state and geodynamic characteristics of the process of division of the southeast margin of the Dabie orogenic belt are four types of the Mesozoic and Cenozoic sedimentary basins, proposed tl^e formation and evolution of the basin experienced the Middle and Late Triassic foreland basin, as early as Middle Jurassic sag basin, Late Jurassic - Early Cretaceous volcanic - sedimentary basins, Early Cretaceous - Paleogene rift basin stage and the Neogene A total of five stages of depression basin, the new point of view, the unification of the southeast margin of the Dabie Mountains in the Cenozoic basin and mechanism of genetic types of knowledge, understanding of the nature of the deepening basin, the correct assessment of the importance of basin resources.
