RUI: Acquisition of a Rapid Sediment Grain Size Analyzer

0318511柯比该补助金支持在加州州立大学富勒顿分校地质系收购一台基于激光衍射的自动粒度分析仪。 由马尔文仪器公司制造的粒度分析仪，由可变波长激光光源的光具座、大容量样品色散池、PC机控制和数据分析软件组成。 该仪器将支持区域教师和学生在古湖沼学/古气候学方面的研究。 湖泊沉积物的粒度分析有助于解释沉积物沉积的水动力、局部构造和区域古气候条件。 该仪器将立即用于美国西南部以碎屑为主的湖泊的教师和本科生调查，并将产生对了解这个人口稠密和半干旱地区的第四纪和全新世气候动态具有特别重要意义的代理数据。

0318511KirbyThis grant supports the acquisition of a laser diffraction-based automated grain size analyzer in the Geology Department at Cal State Fullerton. The grain size analyzer, manufactured by Malvern Instruments, Inc., consists of an optical bench with variable wavelength laser light sources, a large volume sample dispersion cell, a PC computer for control, and software for data analysis. The instrument will support regional faculty and student research in paleolimnology/paleoclimatology. Grain size analysis of lake sediments helps to interpret the hydrodynamic, local tectonic, and regional paleoclimate conditions under which the sediments were deposited. The instrument will find immediate use for faculty and undergraduate student investigations of clastic-dominated lakes of the southwest U.S. and will yield proxy data of particular significance to understanding Quaternary and Holocene climate dynamics in this populated and semi-arid region.***
