Sensitive Grain Size and its Environmental Significance of Modern Mud Patches in Southern and Northern Parts of the Yellow Sea

  • 摘要: 用激光粒度仪对南黄海中部(YSZD01孔)与北黄海西部(B45孔)泥质区沉积物短柱样进行高分辨选样(0.5 cm)的粒度测试与分析,并对柱样进行210Pb测年分析.B45孔柱样沉积时间为1913~2010年,沉积物以粉砂为主,粒度参数垂向波动较大.YSZD01孔柱样沉积时间为1909~2012年,沉积物为泥与砂质泥,粒度参数垂向变化较小.两孔在1958年、1971年、1980年左右砂含量突增,很可能归因于强度大的寒潮,其增强了黄海两泥质区的水动力环境,导致两孔在这些年份左右的粗颗粒沉积物含量突增.用粒级—标准偏差法得到B45孔沉积物敏感粒级组分为15.6~71.8 μm,YSZD01孔沉积物敏感粒级组分为23.7~500.0 μm,用其作为东亚季风变化的指标,显示自1910年代以来东亚冬季风强度增强,两孔在1925~1935年、1955~1964年、1974~1977年、1982~1986年这四个时期敏感粒级含量出现增加趋势,对应冬季风强度增强较为明显.从岩芯粒度来看,季风强度的变化体现为敏感粒级组分含量变化,季风频率的变化体现为敏感粒级含量波动的程度.

    摘要: 用激光粒度仪对南黄海中部(YSZD01孔)与北黄海西部(B45孔)泥质区沉积物短柱样进行高分辨选样(0.5 cm)的粒度测试与分析,并对柱样进行210Pb测年分析.B45孔柱样沉积时间为1913~2010年,沉积物以粉砂为主,粒度参数垂向波动较大.YSZD01孔柱样沉积时间为1909~2012年,沉积物为泥与砂质泥,粒度参数垂向变化较小.两孔在1958年、1971年、1980年左右砂含量突增,很可能归因于强度大的寒潮,其增强了黄海两泥质区的水动力环境,导致两孔在这些年份左右的粗颗粒沉积物含量突增.用粒级—标准偏差法得到B45孔沉积物敏感粒级组分为15.6~71.8 μm,YSZD01孔沉积物敏感粒级组分为23.7~500.0 μm,用其作为东亚季风变化的指标,显示自1910年代以来东亚冬季风强度增强,两孔在1925~1935年、1955~1964年、1974~1977年、1982~1986年这四个时期敏感粒级含量出现增加趋势,对应冬季风强度增强较为明显.从岩芯粒度来看,季风强度的变化体现为敏感粒级组分含量变化,季风频率的变化体现为敏感粒级含量波动的程度.
