| 摘 要： | 通过对水峪贯三叠系下统刘家沟组及和尚沟组的古地磁学研究，建立了该地层段的极性地层柱，极性柱具有混合极性的特点.其中刘家沟组正反极性的组合格式与前人在鄂尔多斯盆地的结果基本一致，但和尚沟组差别较大.根据特征剩磁确定的早三叠世刘家沟组的古地磁极位置经纬度分别为347.5°和6.5°，这与前人在太原西山三叠系下统的研究成果，古地磁极位置经纬度348.3°，61.°大体一致.

| Abstract: | Magnetostratigraphy of Liujiagou Group and Heshanggou Group of Lower Triassic has in Shuiyuguan of Jiaocheng county,Shanxi,China has been established. The magnetic polarity column has a mixed polarity character. During the lower Triassic period,the polaritiy started with a normal polarity. The combination of normal and reversed polarities in Liujiagou Group is basically the same as the results from Erdos. The longitude and latitude of the average pole for Liujiagou are 347.5°,69.0°,basically same as the previous result:348.3°,61.9° for Taiyuan of North China. |
