Abstract

The purpose of this study is to examine mineralogical properties of the soft clay that is distributed widely in Samsan area, Ulsan. XRD analysis were examined to find the quantities of the clay minerals. And XRF, SEM and EDX analysis were also examined to investigate the chemical compositions and the structures of the clay. The properties of the samples from 2 sites in Samsan area were that the minerals of the clay were illite, kaolinite, chlorite, smectite and etc.. The plenty of illite has 38 to 53% of content in whole study area. And kaolinite had 18 to 30%, chlorite had 15 to 25%, and smectite had 4 to 12% of content, respectively. The results of SEM observation showed that appearances of Ulsan clay were sheet, plannar or needle form. Ulsan clay included the salt crystal of cubic and the foraminifera, which were related with the content of organ.
