通过对辽东半岛坡积物、红色风化壳两类沉积物磁化率的测试,揭示了研究区晚新生代以来沉积物磁化率的垂向变化特征及空间分异特征,并初步探讨了其所反映的沉积环境及其古气候变化信息。研究表明:辽东半岛坡积物S1~S4剖面、红色风化壳S5~S6剖面的质量磁化率平均值分别为71.75×10-8、65.81×10-8、68.17×10-8、151.70×10-8和305.06×10-8、473.26×10-8m3/kg,频率磁化率平均值分别为10.77%、9.67%、9.46%、10.79%和14.44%、14.95%;辽东半岛坡积物的质量磁化率值的变化特征、辽东半岛坡积物和红色风化壳剖面的频率磁化率值的变化特征一定程度上反映了其形成时的古气候信息。
Based on the tests of susceptibility of sediments and red weathering crusts in the Liaodong Peninsula, the vertical variations and spatial differentiation characteristics of sediment susceptibility since the Late Cenozoic are revealed, Sedimentary environment and paleoclimate change information. The results show that the average values of mass magnetic susceptibility of S1 ~ S4 section and S5 ~ S6 section of red weathering crust of Liaodong Peninsula are 71.75 × 10-8,65.81 × 10-8,68.17 × 10-8,151.70 × 10- 8 and 305.06 × 10 -8,473.26 × 10-8m3 / kg, respectively. The average values of frequency magnetic susceptibility were 10.77%, 9.67%, 9.46%, 10.79% and 14.44%, 14.95%, respectively. The mass susceptibility The changing characteristics of frequency, the changing characteristics of frequency susceptibility values of the Liaodong Peninsula slope sediments and the red weathering crust profile to some extent reflect the palaeoclimate information during its formation.
