Late Miocene–Pliocene Paleoclimatic Evolution Documented by Terrestrial Mollusk Populations in the Western Chinese Loess Plateau
The Neogene eolian deposits in the Chinese Loess Plateau (CLP) are one of the most useful continental deposits for understanding climatic changes. To decipher Late Neogene paleoclimatic changes in the CLP, we present a terrestrial mollusk record spanning the time interval between 7.1 and 3.5 Ma from the western CLP. The results indicate four stages of paleoclimatic evolution: From 7.1 to 6.2 Ma...
متن کاملMagnetic fabric from Red clay sediments in the Chinese Loess Plateau
Well-distributed eolian red clay in a wide area of northern China is believed to imply the onset of an ancient East Asian monsoon system since Late Miocene. Two continuous red clay sequences spanning the time interval 7-2.6 Ma and 11-2.6 Ma in the Chinese Loess Plateau was investigated to determine the magnetic orientation and grain alignment in the primary fabric of eolian sediments. The north...

متن کامل34. Magnetostratigraphy of Upper Cenozoic Sediments from Leg 145, North Pacific Ocean
Paleomagnetic measurements were performed on whole cores and discrete samples from approximately 4 km of sediment recovered during Leg 145 of the Ocean Drilling Program. The obtained magnetic polarity sequences enabled the establishment of a chronostratigraphic framework from the middle Miocene (about 18.3 Ma) to the present. The quality of the magnetic record is related directly to the sedimen...
متن کاملTetraether biomarker records from a loess-paleosol sequence in the western Chinese Loess Plateau
The ubiquitous occurrence of glycerol dialkyl glycerol tetraethers (GDGTs) in soils and their ability to record temperature and environmental changes offer the prospect of independently reconstructing continental paleotemperature and paleoenvironment from the loess-paleosol sequences (LPS) from the Chinese Loess Plateau (CLP). In this study we present records of GDGT-derived proxies for the las...
