Neogene Paleoclimatic Changes in Response to Tectonism in the Himalayan Gyirong Basin, China

摘要

The Gyirong basin is one of the east-westward extensional basins distributed among the high Himalayas, where a suit of alluvial- and fluviallacustrine deposits (Danzengzhukang Formation and Woma Formation), and a Hipparion fauna along with molluscs, ostracods and pollen were found in Neogene sequence. Results of zircon and apatite fission track thermochronology and palaeo-magnetostratigraphic results in this basin bracket the age interval of the section most reasonably between 10 and 1.7 Ma.
