摘　　要：依据塔里木盆地中部 KT2号钻孔的岩石地层、磁性地层和测年数据等资料 ,探讨了区域地层沉积旋回特征、盆地沉降的阶段性 ,判别出了松山和高斯极性带内分别存在 4个和 2个极性亚带 ,据此建立了塔里木盆地上新世 3.4 Ma以来的地层格架。Based on the data on lithostratigraphy, magnetic stratigraphy and dating from KT2 drill in the middle part of the Tarim Basin, this paper mainly deals with the characters of sedimentary cycles and the stages of the basin subsidence in the region. The results indicate that there existed 4 polarity subzones in the Matsuyama Polarity Zone, there existed 2 polarity subzones in the Gauss Polarity Zone. Moreover, the stratigraphic framework since Pliocene (3.40Ma) were established in the Tarim Basin.
