| 摘 要： | 本实验采用激光粒度分析仪对福建漳浦前湖湾QHP剖面进行第四纪沉积物粒度分析,并绘制出频率曲线图和概率累积曲线图,进行沉积动力的解释,综合实地观察,该剖面岩性,有孔虫、硅藻分析结果14C年代测定等实验资料,得出该剖面从下往上的演化过程:①晚更新世晚期的浅河流沉积;②晚更新世晚期的湖泊沉积;③晚更新世晚期至全新世海岸风砂沉积.

| Abstract: | The grain size in the deposit sediment on quaternary period from QHP section in the Qianhu small bay of Zhangpu in Fujian was studied using laser granularity instrument.The frequency diagram of curves and the probability accumulation diagram of curves were drew up in addition to the deposition power that was explained.Integrating with spot inspection,section lithology,foraminifera,diatoms and the experimental materials by the carbon 14 dating,we suggests that the evolution process from bottom upward the QHP section is,1.the shallow rivers deposit in the Later period of Epipleistocene,2.the lacustrine deposit in the Later period of Epipleistocene,3.seacoast wind deposit since the later period of Epipleistocene to Holocene. |
