Abstract
The Liuqu Conglomerates consist of a suit of terrestrial molasse deposits formed in a foreland basin of the Himalaya-Tibet orogenic belt before the collision of India and Eurasia. These deposits record considerable geological information regarding the late tectonic evolution of the Neotethyan ocean. The palynological study of interlayers of mudstone and mud-sandstones indicates an Oligocene age. The palynological assemblage consists mainly of deciduous broad-leaved angiosperms, with some coniferous gymnosperms and evergreen broad-leaved angiosperms. The deposits reflect a broad-leaved deciduous forest or mixed with conifer-broad-leaved forest ecotypes, showing a warm-temperate or temperate zone climatic environment. This work provides significant new information about the tectonic evolution, paleogeography, and paleoenvironment of southern Tibet during the Cenozoic.
