内容記述 We have tried to clarify the influence of diatom tests on the grain size distribution of muddy lacustrine sediments measured by laser diffraction size analyzer on the basis of comparison between silica-dissolved sample and silica-undissolved sample or the same sediment. Tested sediments are two cores taken from the center or Lake Kizaki, Nagano Prefecture. Bimodal distribution or grain size is common feature or the sediments. Coarser mode centered around 150 -200 microns become more distinct and is increased in ratio after diatom dissolution. This would be explained by the fact that diatom tests of small size are abundant and affect to increase the ratio of finer mode of grain size distribution. In addition, when the tests of diatom tests such as Cyclotella, mostly around 10-20 microns in size, are predominant, the peak or the finer mode moves to coarser side after biogenic silica dissolution. On the contrary, when large elongated diatom such as Fragilaria and Synedra, mostly 60-80 micrometers in length, are abundant, the peak of finer mode moves to finer side after silica dissolution.
