| 摘 要： | 根据2008年7月对从前湖湾古树林埋藏剖面和钻孔连续采集的142个样品进行粒度参数测量,分析了古树林成因和埋藏地的沉积环境变迁。用前湖湾周边已知沉积相:海滩、入海河流、河口浅滩、海岸沙丘以及滨海沼泽样本作为目标判据,将平均粒径Mz、标准偏差σ1和峰态Kg设为判别参数,与剖面和钻孔样品进行聚类判别,结果表明,42KaBP前湖湾古树林被海湾—河口相变过程埋藏,经历了6个阶段:河口浅滩阶段、浅滩—沙丘交替阶段、浅滩—河流演变阶段、淡水沼泽阶段、海滩沙丘阶段和现代风沙阶段,是气候—环境演变导致了前湖湾沉溺古树林的埋藏。

| Abstract: | 142 samples from the section and bored hole at Qianhu Bay are collected and their grain-size parameters,mean particle size,standard deviation and kurtosis are tested in July 2008. Parameters of other specimen from beach,steam,estuarine shallow,sand dunes and freshwater swamps around the bay have also been tasted and taken as the target criterion. Cluster analysis between samples and target criterion shows that the forests were buried by bay-estuary changes. It experienced 6 stages:estuarine shallow stage,sh... |
