Magnetostratigraphic dating of loess deposits in china

Because these floodplains consist of sediment containing a high content of glacially ground flour-like silt and clay, they were highly susceptible to winnowing of their silts and clays by the wind.

Once entrained by the wind, particles were then deposited downwind.

But even the chronostratigraphical position of the last interglacial soil correlating to marine isotope substage 5e has been a matter of debate, owing to the lack of robust and reliable numerical dating, as summarized for example in Zöller et al.

Loess grains are angular with little polishing or rounding and composed of crystals of quartz, feldspar, mica and other minerals. Loess deposits may become very thick, more than a hundred meters in areas of China and tens of meters in parts of the Midwestern United States.

It generally occurs as a blanket deposit that covers areas of hundreds of square kilometers and tens of meters thick.
