3.Through the analysis of subsidence history in the north of western Ordos basin, as a result of the terranes northward accretion and the successive collision of the Baykala block in the Middle Triassic, the Qiangtang block in the Late Triassic, the Lhasa block in the Middle Jurassic, the Gangdese block in the Cretaceous and the subduction of Izanagi plate in Yanshanian period, the studied region became a intracontinental foreland basin from Late Triassic to Cretaceous.
摘要通过对鄂尔多斯盆地西缘北段沉降史的分析可知,晚三叠世-白垩纪,由于中三叠世巴颜喀拉地体、晚三叠世羌塘地体、中-晚侏罗世拉萨地块、白垩纪冈底斯地体连续向北增生、碰撞以及燕山期伊佐奈岐板块的俯冲,盆地西缘北段的响应显示为陆内前陆盆地的特征。
4.(6)The tectonic evolution of the Xidamingshan uplift can be mainly divided into three stages: Sinian period to Silurian period is the foundation evolution stage, Devonian period to mid-Triassic period is the regional extension-depression stage and late Triassic period to Cenozoic era is the compressional structural deformation and uplift-erosion stage.
