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尺寸分析仪器。该设备用于分析在入门地质学，地貌学，水文地质学和独立学生研究中协调的实地/实验室练习中收集的沙子和细颗粒沉积物样品。它允许学生对地质材料进行详细和准确的分析，包括规定数据减少和分析结果的图形呈现，花费最少的时间和样品制备。通过向学生介绍现代分析技术，自动化沉积物分析增强了现有的地质学课程。粒度分布是地质学家用来描述沉积过程或沉积环境的重要工具。此外，粒度和分选是疏松矿床渗透率的重要控制因素。

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.
