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

  • 摘要: 磁性地层学测量与对比研究表明:(1)静乐贺丰地点的静乐红土即为红色土A层,记录了Gauus正极性带,年龄为2.50~3.00Ma,时代为晚上新世。榆林剖面红土记录了Gauus正极性带与Gilbert负极性带,年龄为2.50~5.00Ma,时代为上新世。(2)静乐剖面红色土B层相当于黄土—古土壤序列WS—1,WS—2,WS—3或S15—S32地层段,记录了Olduvai与Reunion正极性带,年龄约1.20~2.30Ma,时代为早更新世早期。(3)榆林河沿岸红色土C带,主体为离石黄土,大致为S1—L15地层段,部分地段出露午城黄土。
    Abstract: 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.
