| 摘 要： | 论述了福建省莆田县忠门乡苦鹅头村东南海岸一套全新世含生物碎屑的砂、砾岩的沉积特征、沉积环境及其对海平面变化的反映。砂、砾岩层可划分成上、下两段，具有不同的成因。下段（０￣２．６ｍ）为海滩沉积，形成于中全新世高海平面时期。上段（２．６￣８ｍ）是全新世晚期（约３￣２ｋａ ＢＰ）的风沙沉积，内部夹有两个弱土壤化层，表明在风沙沉积作用过程中有过两次短暂的气候波动。

| Abstract: | A suite of Holocene sandstone and conglomerate, distributed on the southeast coast of Kuetou, Zhongmen, Putian County, Fujian Province, is dealt with in this paper with respect to its sedimentary characteristics, depositional environments and response to sea level changes. The sequence can be divided into two members, which are attributable to different origins. The lower member (0 2.6 m) comprises beach sediments and was formed during the high sea level stand of mid Holocene. The upper member (2.6 8 m) resulted from the late Holocene (about 3 to 2 ka BP) eolian sedimentation. Two weakly pedogenic beds within this part suggest two short term climatic fluctuations in the prevailing eolian activity. |
