| 摘 要： | 对河北邯郸HZ-S孔第四纪沉积物样品采用MS-2000型激光粒度分析仪进行测试和系统的粒度分析,研究结果表明:沉积物总体形成于水动力平稳低能的河湖相沉积环境。与典型的古洪水平流沉积物粒度特征进行对比,显示具有古洪水平流沉积特征。物质来源主要是以洪水为介质动力的河流冲积物(或洪积物),沉积物组成总体以粉砂为主,主要由悬移质构成,沉积物分选较好,粒度分布多为单峰型。其次是以地表径流为介质动力的陆源碎屑物质,由于短距离搬运,造成沉积物分选较差,跃移组分较多,粒度分布多为双峰型。纵向上沉积物平均粒径与<32μm细颗粒级百分含量呈同步正相变化,其大小主要受<4μm的粘土含量变化所控制。

| Abstract: | Grain size of HZ-S core quaternary sediments were analyzed with the Malvern Mastersizer 2000 particle size analyzer in Handan City,Hebei Province.The results showed that the sedimentary environment was fluvial and lacustrine facies and it's sedimentation hydrodynamic force was stationary and low energy.The sediments had basic characteristics of palaeoflood slackwater deposits by comparing with typical characteristics of grain size for palaeoflood slackwater deposits.Their source areas of the sediments were ... |
