영문 초록

In this paper, I have researched on the geochemical character of twenty fourth sediments distributed research area. The results were as follows. I. The mean size is 3.14'" at Keum river, 5.72 '" Dongjin river, 5.36 '" Mankyung river, with fine sand. It has been distriubuted with coarse silt. II. The sorting is moderately sorted at Keum river, but it is poor sorted at Dongjin and very poor sorted at Mankyung river. III. The skewness were appeared negative skewed at upstream at Keum river but the other sector has been appeared very positive skewed. IV. The kurtosis were very leptokurtic skewed at whole research sector. V. Most elements except CaO. K2O. CaC03. among the character of element chemical composition has a good relation on the size of sediment according to the rariation of contents. Al2O3, Fe203, MgO, Na2O, TiO2. P2O5 etc were increased predominently due to the finness of the size. It showed hish contents K2O at Keum river, Al203, CaO at Dongjin river Fe203, MgO, Na2o, P205, CaCO3, Organic etc at Mankyung river. VI. The chemical component of trace elements has high relativity in the sediments size with Cr, Ni, V, Zn but In the coarse sediments, It showed high relativity. The space distribution of research sector showed high contentivity Ba, Sr at Keum river Ni, Cr, V, Cu, Ph, Zn at Dongjin, Mankyung river. VII. All elements in the research sector except K2O, Ba, showed Jess world mean contents in shallow bottom sediment, however, all elements in coarse sediment are axious to pollutarize to the specities minerals.
