Abstract:Geodynamic models of petroleum-bearing basins are discussed and several problems are emphasized in this paper.1. The advances in the geodynamic study of sedimentary basins enable geologists to propose a scheme of classification of petrolemu-bearing basins on the basis of the positions of basins in a tectonic plate and the geodynamic models. 2. Although we have some plausible geodynamic models of Paleozoic intracratonic basins, we still lack connvincing explanation for their formation mechanism. 3. From an integrated analysis of the chemical composition of volcanic rocks, geothermal field, structural deformation, lithosphere structure and regional plate tectonic setting of the intracontinental rift, six geodynamic models of formation of continental rifts have been constructed. 4. The formation of foreland basins is closely related with their neighbouring oro-genic belts. The geodynamic model is the flexural response of the continental lithosphere to the tectonic load of the thrust-fold belt. 5. Strike-slip extensional basins closely resemble extensional basins modified by strike-slip faults. Because of the resemblance, many extensional basins are mistaken for pull-apart basins. Credible identification calls for integration of criteria in plan with those in section.
