摘要
本文从龙门山的形成发展入手,论述了四川盆地的演化过程。认为上扬子区自印支期以来,经历了前陆盆地和拗陷盆地之后,在特提斯和滨太平洋构造城以压应力为主的长期作用下,于喜山早期形成了四川构造盆地;成盆后的演化集中反映在构造形变上。进而据盆地的演化、形变特点,预测了油气勘探领域。
Starting from the formation and development of Longmen Mountains, this paper elucidates the evolu- tion process of Sichuan Basin and considers that after having been undergone foreland basin and depression basin since Indo-China Time, upper Yangzi area was changed into Sichuan structural basin in early Hi- malayan Movement by a long-term action compression stress produced between Tethys and coastal Pacific plate. The evolution after the basin had been formed is concentratively reflected on the structural deforma- tion. And then according to the basin evolution and deformation characteristics, the domains for oil and gas exploration are forecasted.
