| Advances in Sequence Stratigraphy of Tibet |
| So far, analyses of sequence stratigraphy in Tibet have only been associated with second and third order sequences of the Mesozoic. Based on facies, paleontology, magnetism stratigraphy and geological events from outcrop sections, this paper has dealt with models and mechanisms of sequences from Triassic to Cretaceous. The advances made are as follows: ① Sequence frameworks are established for the Mesozoic. ② It is revealed that basins of different ages and types have remarkably different quantities, structures and types of sequences.③ Important achievements have been made by the combined studies of sequence and magnetism stratigraphy. The following three aspects are expected to develop in future in sequence stratigraphy of Tibet: ① High resolution sequence stratigraphy is to be used to build up the Jurassic Tertiary sea level curves of Tibet.② It is possible to apply sequence stratigraphy to new mapping. ③Sequence stratigraphy will be encountered with new challenges from continental dynamics of archipelago arc orogenic models and multi mechanism uplifting models. |
