Abstract The fluvio-lacustrine sequence in the Lanzhou Basin, located at the northeastern margin of the Tibetan Plateau, is a rich source of Oligocene–Miocene mammalian fossils, critical to our understanding of the terrestrial Asian mammal and environmental evolution. While the Miocene mammalian faunas have been dated with magnetostratigraphy, the numerical age of the Oligocene faunas remains controversial. Here, we present new high-resolution magnetostratigraphic records from two fluvio… Expand

Magnetochronology of Mid-Miocene mammalian fauna in the Lanzhou Basin, northeastern Tibetan Plateau: Implications for Asian mammal migration
Abstract The Quantougou (QTG) Fauna in central Lanzhou Basin is an important late Mid-Miocene fauna on the northeastern Tibetan Plateau margin, but its numerical age remains a matter of debate. Here,Expand
Astronomical forcing of lake evolution in the Lanzhou Basin during early Miocene period
Abstract Orbital-scale East Asian summer monsoon (EASM) variability has been extensively investigated in Pliocene-Quaternary loess and marine sediments. In recent years, middle-late MioceneExpand
Orbital climate variability on the northeastern Tibetan Plateau across the Eocene–Oligocene transition
It is concluded that this terrestrial orbital response transition coincided with a similar transition in the marine benthic δ18O record for global ice volume and deep-sea temperature variations and was a response to coeval atmospheric CO2 decline and continental-scale Antarctic glaciation. Expand
Paleogene crustal extension in the eastern segment of the NE Tibetan plateau
Abstract The Tibetan plateau experienced lateral growth in response to the India–Eurasia collision, but uncertainties remain about when and how its present-day margins were formed. It was commonlyExpand
Cenozoic aridification in Northwest China evidenced by paleovegetation evolution
Abstract Although the Cenozoic aridification of the Asian interior was of global significance, the timing of its evolution and the drivers remain controversial. However, knowledge of theExpand


Late Oligocene–Early Miocene magnetochronology of the mammalian faunas in the Lanzhou Basin–environmental changes in the NE margin of the Tibetan Plateau
A high-resolution magnetostratigraphic dating of the Late Oligocene–Early Miocene mammal assemblages from a 233-m thick fluvio-lacustrine section in the Lanzhou Basin located at the northeastern margin of the Tibetan Plateau, China provides considerably more robust ages for three associated land mammalian faunal assemblage.

New magnetochronology of Late Miocene mammal fauna, NE Tibetan Plateau, China : Mammal migration and paleoenvironments
Abstract Lanzhou Basin lies on the northeastern margin of the Tibetan Plateau in western China and is a rich source of Oligocene–Miocene mammalian fossils. Obtaining precise age determinations forExpand
Recent Advances in the Small Mammal Biostratigraphy and Magnetostratigraphy of Lanzhou Basin
The consensus view among geologists is that the Lanzhou Basin sequence of sedimentscontains the Oligocene/Miocene boundary, but where this occurs is unknown. Indeed, this is thecrux of the issuesExpand
Land mammal geochronology and magnetostratigraphy of mid-Tertiary deposits in the Lanzhou Basin, Gansu Province, China
The Lanzhou Basin is situated at the northeast slopes of the Tibetan Plateau, and its basin-fill is expected to reflect the process of uplifting of the plateau like the Siwaliks south to theExpand
Magnetostratigraphy and pavleo-environmental record of Tertiary deposits of Lanzhou Basin
The Tertiary deposits of the Yongdeng section, the Lanzhou Basin were studied by means of magnetostratigraphy. The magnetostratigraphic sequences from Paleocene to Miocene were established, and theExpand

Pulsed growth of the West Qinling at -30 Ma in northeastern Tibet: Evidence from Lanzhou Basin magnetostratigraphy and provenance
The development of Cenozoic basins in the northeast margin of the Tibetan plateau is central to understanding the dynamics of plateau growth. Here, we present a magnetostratigraphy from the LanzhouExpand
Evidence for northeastern Tibetan Plateau uplift between 25 and 20 Ma in the sedimentary archive of the Xining Basin, Northwestern China

Geologic Evolution of the Himalayan-Tibetan Orogen
A review of the geologic history of the Himalayan-Tibetan orogen suggests that at least 1400 km of north-south shortening has been absorbed by the orogen since the onset of the Indo-Asian collisionExpand
