The eolian deposition is one useful index to know the climate change of source region and the atmospheric cycle model at that time.  The eolian records indicated by Al fluxes in the low-latitude ferromanganese crusts are determined by the high-revolution microprobe technique. The results show that the average content of Al fluxes in the ferromanganese crusts during the past 70 Ma is 300.5 μg/(cm²·ka), which has recorded the incompleteness of eolian history in the southern hemisphere and the northern hemisphere.
