Magnetic Proxy of Eurasian Loess Revealing Enhanced Physical Erosion Since the Mid‐Pleistocene Transition

Eolian loess deposits contain valuable information about past climate changes and erosion history in dust source regions. In contrast to the extensive investigations of paleoclimatic implications Eurasian loess, continental has received less attention, particularly on global or hemispheric scales. The present study combines citrate-bicarbonate-dithionite (CBD) magnetic mineral extraction procedures linear regression parameters analyze loess. We find that lithogenic susceptibility Quaternary Central Asia, Europe Chinese Loess Plateau shows synchronous long-term increases since ∼0.6–0.5 Ma, suggesting intensive glacial and/or river incision have occurred surrounding mountains regions after mid-Pleistocene Transition. dramatic increase provides new insights into close relationships between late Cenozoic.
