Distinctive Sedimentary Evolution at the East Edge of the Central Yellow Sea Mud Over the Past 45 kyr: Evidence From Detrital Mineralogy

open access: yesFrontiers in Earth Science, 2022
The central Yellow Sea Mud (CYSM) is a vital part of the coastal sand and distal mud depositional system in the South Yellow Sea (SYS). Previous studies concerning the sedimentary evolution of this area have almost exclusively concentrated on its ...

Sedimentary evolution of the foreland basin in the NE Tibetan Plateau and the growth of the Qilian Shan since 7 Ma

open access: yesGSA Bulletin, 2019
We studied the magnetostratigraphy and sedimentary facies of a 550-m-long drill core from the Jiudong Basin in the NE Tibetan Plateau. Our aims were to reconstruct the late Cenozoic sedimentary evolution of this foreland basin, and to determine the ...
