山东半岛泥质区沉积物敏感粒级分析及其环境意义
|
摘要
基于山东半岛泥质区附近四根岩芯沉积物样品的高分辨率取样(1cm)粒度测试分析资料,分析了粒度频率曲线、粒度参数及其粒度组成特点,采用粒级-标准偏差法提取了沉积物的敏感性粒级,并探讨了研究区沉积物的搬运机制及对东亚冬季风强度的响应。结果表明:山东半岛泥质区沉积物以粉砂为主,砂和粘土的含量变化差异较大,粉砂含量变化较小,主要以跃移加悬浮组分为主。发育了大致相同的三个粒级组分,分别是粒组1(<1.24μm)、粒组2(1.24~20.45μm)和粒组3(28.84~136.47μm),同时提取出粒组3(28.84~136.47μm)为研究区岩芯的敏感粒级,可以作为山东半岛泥质区的环境替代指标。测年数据和环境代用指标分析表明,敏感粒级平均粒径波动的程度可以反映东亚季风强弱变化,同时百年尺度中,北太平洋涛动和东亚冬季风与研究区沉积环境存在着紧密的联系,东亚冬季风较强时,岩心敏感粒级平均粒径呈现粗化趋势,同时与NPO指数呈现相反趋势,应用敏感粒级粒径波动来指示气候变化具有极其重要的意义。
Based on the high resolution sampling(1 cm),we performed grain size analysis on four cores taken in the inner shelf of the Shandong Peninsula.The grain-size frequency curves,particle size parameters and the characteristics of its sediments were analyzed.The sensitivity grain size of sediment was determined by standard deviation method,and their geological implication was Discussed.Three grain size components were recognized at<1.24μm(Component 1),1.24~20.45μm(Component 2),and 28.84~136.47μm(Component 3).And the component 3(28.84~136.47μm)was extracted as the sensitive grain size of the core in the study area,and it can be used as an environmental substitute index in the muddy area of Shandong Peninsula.Analysis of dating data and environment proxies indicate that the variability of the main grain size of sensitive particle size reflects the change of Asian monsoon.Besides,North Pacific Oscillation(NPO)and Asian winter monsoon are closely related with the sediment environment in the study area at century scale.The main grain size of sensitive particle size are coarser when Asian winter monsoon turn stronger and it have a negative correlation with NPO index.Variability of the main grain size of sensitive particle size has vital significance to indicate climate change.
