Description
In east-central Tibet, many Paleogene elongate basins with medium-mini-type are distributed along the large-scale arc-shaped strike-slip belt of the Qiantang-Hengduan Shan-Jinsha-Red River belt. Most of basins are controlled by the regional north-northwest-and south-north-treading faults, and a few basins by the local northwest-or north-northeast-treading faults.
The Tibetan plateau started to enter the development stage of inland basins owing to the Tethys subduction related to the Indo-Asian collision since the Middle-Late Eocene. The collision constrained not only the formation and evolution of Cenozoic basins inner and near eastern Tibet, but also directly the early tectonic uplift in the Tibetan Plateau.
In summary, the combination of the fold-thrust deformation in the setting of contraction, crust shorting, and growth strata suggests that wide and forceful tectonic deformation, magmatic activity, and huge bedded coarse clastic rock accumulation occurred in Paleogene basins in east-central and peripheric Tibet, and may foreshow the start of wide early tectonic uplift due to the Indo-Asia collision at the late Early in Tibetan plateau.
