摘要
山东地区风尘沉积类型多样,在中国风尘沉积系统研究中占有重要地位.其中庙岛群岛横跨胶东半岛与辽东半岛之间的渤海海峡,发育了晚新生代以来各个阶段风尘堆积:红色风化壳、棕红土、离石黄土、马兰黄土和全新世黄土.综述了山东庙岛群岛粉尘堆积各沉积层的沉积特征及粒度、矿物组成、磁化率、孢粉等指标目前已取得的研究成果,并对今后研究进行了展望,认为研究重点在于高分辨率年代学和环境代用指标.
The eolian deposits in Shandong area occupies an indispensable part in eolian deposits system of China due to its variety of genetic types. Miaodao Islands lie across the Bohai Gulf between Jiaodong and Lia odong Peninsulas. They have developed deposits during the Late Cenozoic time. The sediments here can be di vided into red weathered crust, brownish red loam, Lishi Loess, Malan Loess and Holocene Loess. This paper reviews the characteristics of the sediments and the main progress of substitutive indexes such as grain size, mineral composition, magnetic susceptibility, sporepollen. In addition, the prospect of the research emphasis for the future is also indicated.
