EPR studies of Mn~(2+) in the Loess Plateau of central China: Implication for variation of the East Asia summer monsoon

Mn2+ EPR intensity recorded in the Chinese loess-paleosol sequence shows close correlation with magnetic susceptibility and Sr content as well as the oscillation of paleoclimate. Thus Mn2+ EPR signal can serve as an indicator sensitive to the East Asia summer monsoon intensity fluctuations.
