鄂尔多斯盆地构造演化及古地理特征研究进展
Study Progress in Tectonic Evolution and Paleogeography of Ordos Basin
摘要
Abstract
Ordos Basin is a typical superimposition basin in the edge of cratonin the west of North China Plate, its development and evolution came together with North China plate, was controlled by the evolution of the many - periods opening and closing of ancient sea trough in the basin edge and has its own peculiarity and complexity. Recent studies show that So far the development and evolution of Ordos Basin has undergone eight stages:The formation stage of crystalline basement in Archean to early Proterozoic; The rifting stage in Early to middle Mesoproterozoic, in which continental margin rifls and inlracontinental aulacogens grew; The continental convergence stage in late Mesoprolerozoic to early Neoproterozoic, in which the basin uplifted, causing sedimentation lacuna; The basin margin rifting and intracontinental depression stage in Middle Neoproterozoic to middle Ordovician of Paleozoic, in which marine carbonate platform deposition mainly grew;The collisional orogenic stage in the basin margin in late Ordovician to early Carboniferous, in which the basin uplifted and suffered erosion; The rifting stage on the margin in late Carboniferous to the end of Permian, in which paralic depositition mainly grew;The depression stage in Mesozoic, in which the basin margin uplifted and tilted and fluvial, delta and lacustrine facies grew;The basin margin faulting stage in Cenozoic. In the stages above, ancient tectonic framework in middle Proterozoic had an important impact on fault extension, deposition evolution, fluid migration and aggregation in the late basin.关键词
