Previous paleomagnetic studies have shown that the records of MatuyamaGauss(M/G) reversal event in Chinese loess are asynchronous
some located in loess
while the others located in red clay. This phenomenon will partially lead to the uncertainties in reconstructing the chronology of loess and correlating loess climatic proxies with marine sediments. To clarify our knowledge on the M/G reversal in loess
some representative section studies on the M/G reversal are carefully analyzed in this paper
using the magnetic susceptibilitydepth curve to synthesize the different sections. Comprehensive results show that M/G reversal is generally recorded in loess L

layer
suggesting that the asynchronous feature of M/G reversal record in loess is possibly attributed to the different loess stratigraphic division schemes. According to this idea
the stratigraphic classification scheme of the classic Luochuan and Xifeng loess is partially modified. Finally
the records of M/G reversal in Chinese loesspaleosol are further compared with that of the marine sediments. The perspective of using

Be to trace the M/G polarity reversal in loess is briefly introduced.
