Abstract. The global climate system experienced a series of drastic changes during the Cenozoic. In Asia, these include transformation from zonal pattern to monsoon-dominated pattern, disappearance typical subtropical aridity, and onset inland deserts. Despite major advances in last two decades characterizing understanding phenomena, disagreements persist relative timing, behaviors underlying causes. This paper addresses issues mainly based on lines evidence. First, we compiled newly...
The North China craton and the Yangtze (South China) both contain Archean rocks in eastern China. Unlike craton, where are widespread, exposed only known Kongling terrain (360 km<sup>2</sup>). Zircon U-Pb ages Lu-Hf isotopic compositions of three granodioritic-trondhjemitic gneisses metasedimentary from were analyzed by LA-ICP-MS LA-MC-ICP-MS. Igneous zircons one trondhjemitic gneiss north have an age 3302±7 (1σ) Ma. Evidence cathodoluminescence imaging, variations Th/U degree discordance...
Abstract. Asian terrestrial records of the Eocene-Oligocene Transition (EOT) are rare and, when available, often poorly constrained in time, even though they crucial understanding atmospheric impact this major step Cenozoic climate deterioration. Here, we present a detailed cyclostratigraphic study continuous continental EOT succession deposited between ~35 to 33 Ma Xining Basin at northeastern edge Tibetan Plateau. Lithology supplemented with high-resolution magnetic susceptibility (MS),...
The Chinese Loess Plateau (CLP) covers an extensive area over 440,000 km 2 and provides unprecedented terrestrial record of Neogene climate. However, it is still unclear whether the provenance these loess deposits uniform or contains spatial temporal differences. Here this addressed by comparing detrital‐zircon age spectra typical paleosol samples from three distant sites located at western, middle, southeastern parts CLP. Our results reveal that zircon not only change between layers but...
Abstract The first major build-up of Antarctic glaciation occurred in two consecutive stages across the Eocene–Oligocene transition (EOT): EOT-1 cooling event at ~34.1–33.9 Ma and Oi-1 ~33.8–33.6 Ma. Detailed orbital-scale terrestrial environmental responses to these events remain poorly known. Here we present magnetic geochemical climate records from northeastern Tibetan Plateau margin that are dated precisely ~35.5 31 by combined magneto- astro-chronology. These suggest a hydroclimate...
The Nihewan Basin (40°N) in North China is a rich source of Early Pleistocene Paleolithic sites and thus key area for studying early human evolution high‐latitude (from an perspective) East Asia. Here high‐resolution magnetostratigraphic investigation carried out on fluvio‐lacustrine section the northeastern Basin, which contains Feiliang Lanpo sites. Paleomagnetic results suggest that this records lower portion Brunhes polarity chron upper Matuyama chron. Furthermore, Jaramillo subchron...
The Nihewan Basin in North China has a rich source of Early Pleistocene Paleolithic sites. Here, we report high-resolution magnetostratigraphic dating the Shangshazui site that was found northeastern 1972. artifact layer is suggested to be located Matuyama reversed polarity chron just above upper boundary Olduvai subchron, yielding an estimated age ca 1.7–1.6 Ma. This provides new evidence for hominid occupation earliest Pleistocene. hominids are argued have lived habitat open grasslands...
The fluvio-lacustrine sequences in the Nihewan Basin of North China (known as Formation) are rich sources Early Pleistocene Paleolithic sites and mammalian fossils Fauna sensu lato), which offer an excellent opportunity to investigate evolution early humans land mammals East Asia. Also abundant provide clues about general environmental climatic setting humans. Among (sensu Daodi is one most complete oldest eastern Basin: seven fossil-bearing layers Formation have been described. Except for a...
