The foundation of Nokson industrial complex prepared are is composed of unconsolidified sediments including clay minerals, quartz, plagioclase and calcite. the mineral compositions vary dependent on the depth. That is, at the depth of 0-15 meters quartz and plagioclase are more abundant than clay minerals, at the level of 15-40 meters clay minerals and calcite are more than quartz and plagioclase, and at the depth deeper than 40 meters, the amounts of quartz and plagioclase increase slightly and that of clay minerals decrease. Clay minerals of the clayey sediments include illite, smectite, kaolinite and chlorite. Of those illite (33-65%) is the most abundant, kaolinite (15-36%) and chlorite (12-28%) are the intermediate, the least is smectite (0.3-19%). At 17-40 meters´ depth, smectite is abundant and kaolinite is little relatively. The result of cation exchange capacity analysis shows that the relationship of Ca>Na=Mg>K and the trend of especially low Cation´s exchngeable capacity at the depth deeper than 40 meters. The pH of suspension is various between 3-9 and decrease to 3-5 at the depth deeper than 40 meters. The electric conductivity of suspension is also various according to the depth. The result of soil test of clay sediments, water contentshows that liquid limit, plastic limit, particle size, unconfined compressive strength, coefficient of strain varies depending on the depth. The correlation analysis and factor analysis of all the data suggest that water content, liquid limit, plastic limit, plastic index, flow index, activity are correlated with the contents of smectite and calcite, liquid limit, consistency index, dry unit weight and void ratio correlated with pH of suspension, contents of illite and kaolinite, unconfined compressive strength and coefficient of strain with correlated exchangeable cation, toughness index and specific gravity correlated with contents of quartz, plagioclase, clay minerals respectively. In summary, soil analysis data are correlated with the mineral composition and chemical characteristics. The variation of mineralogical, geochemical, engineering properties of soil with the depth are probably due the differing sediments of different sedimentary environment. that is, these variations are considered to be correlated with the sedimentary environment change resulting from the change from continental environment to ocean environment due to the transgression of the interglacial period after the regression the latest glacial period.
