摘要
选择兴化市乌巾荡(湖泊),在湖滨采集地表20cm至280cm的晚全新世沉积层连续样品,经物理鉴定后,又进行粘土、粘土矿物X衍射、磁化率、硼含量,部分岩芯磨片镜下观测等多元测试分析,提出了乌巾荡湖相沉积层中鉴别洪水沉积的标志与初步结论.
Studying on a river-course-style lake,Wujindan lake in Xinghua, the author collect late holocene deposit samples 20-280cm in the means of undergroumd, analyse these samples observation with eyes,grain size,clay mineral observation bytx-ray,mineral magnetic,the content of B, gromdomg samples, then but forward the marks of floodwater deposit in the samples.
