THE RELATIONSHIP BETWEEN THE RED SOIL AND LOESS PALEOSOL SEQUENCE IN JINGLE, SHANXI PROVINCE, AND YULIN, SHAANXI PROVINCE

Magnetostratigraphic measurements and correlation of layers A, B and C of red soil show: （1） the Jingle red soil at Jingle and Hefeng is just layer A of red soil, in which the Gauss normal polarity zone is recorded, with an age of 2.50～3.00 Ma, corresponding to late Pliocene. Red soil in the Yulin section records the Gauss normal and Gilbert reversal polarity zones, whose age is 2.50～5.00 Ma, corresponding to Pliocene. （2） Layer B of red soil in the Jingle section, which corresponds to layer W S 1 , layer W S 2 , layer W S 3 or layer S 15 S 32 of the loess paleosol sequence, records the Olduvai and Reunion normal polarity subzones, and the age is 1.20～2.30 Ma, corresponding to early Early Pleistocene. （3） Layer C of red soil along the Yulin River bank corresponds mainly to the Lishi loess, about the S 1 S 15 interval, and partially to the Wucheng loess.
