Automated Sediment Size Analysis: Analytical Experience for Undergraduates in Geology

地质系正在购买一台计算机控制的 粒度分析仪 该设备用于 分析了在2000年至2001年期间收集的沙子和细粒沉积物样品， 在地质学导论中协调实地/实验室练习， 地貌学、水文地质学和独立学生 research. 它可以让学生进行详细和准确的 地质材料分析，包括数据准备 分析结果的简化和图形表示， 最少的时间花费和样品制备。 自动沉积物分析增强了现有的课程， 通过向学生介绍现代分析地质学 技术. 粒度分布是重要的 地质学家用来描述 沉积过程或沉积环境。 在 此外，粒度和分选是重要的控制因素， 松散沉积物的渗透率。

The Department of Geology is purchasing a computer controlled size analysis instrument. This equipment is used in the analysis of sand and fine grained sediment samples collected in coordinated field/lab exercises in introductory geology, geomorphology, hydrogeology and in independent student research. It allows students to conduct detailed and accurate analyses of geologic materials, including provisions for data reduction and graphic presentation of analytical results with a minimum of time expenditure and sample preparation. Automated sediment analysis enhances the existing curriculum in geology by introducing students to modern analytical techniques. Grain size distributions are an important descriptive tool used by geologists to characterize depositional processes or environments of deposition. In addition, grain size and sorting are important controls on permeability of unconsolidated deposits.
