摘要: 三塘湖盆地的构造演化经历了中泥盆世—晚泥盆世早期洋壳俯冲、晚泥盆世晚期—早石炭世残留海盆地和晚石炭世以来的板内构造演化等三个大的演化阶段。其中,板内构造演化阶段又分为4个亚段,即晚石炭世—早二叠世碰撞造山亚段、晚二叠世—三叠纪“A”型俯冲与前陆盆地形成亚段、侏罗—白垩纪应力调整与坳陷形成亚段和第三纪以来的“A”型俯冲与再生前陆盆地形成亚段。相应地叠合了6种不同类型的盆地。即中泥盆世—晚泥盆世早期的弧后盆地、晚泥盆世晚期—早石炭世的残留海盆地、晚石炭世—早二叠世与挤压有关的山前坳陷盆地、晚二叠世—三叠纪的前陆盆地、侏罗纪—白垩纪的坳陷盆地和新生代以来的再生前陆盆地。

Abstract:

The tectonic evolution of Santanghu basin has undergone three major stages: (1) Oceanic subduction during Middle Devonian and the early phase of Late Devonian; (2) Formation of remnant sea basin from the late phase of Later Devonian to Early Carboniferous; (3) Intra-plate tectonic evolution since Later
Carboniferous. The last stage can be further divided into four sub-stages: collision and mountain formation during Late Carboniferous-Early Permian, A-subduction and foreland basin formation during Late Permian-Triassic, stress adjustment and sag-basin formation during Jurassic-Cretaceous, and Aubduc-
tion and regenerative foreland basin formation since Tertiary.Accordingly, six different, stacking prototype basins, namely back-arc basin, remnant sea basin, fore-mountain sag basin,foreland basin, simple sag basin and regenerative foreland basin,have been formed.

Key words: Santanghu basin, prototype, tectonic evolution, foreland basin, A-subduction
