영문 초록

In this paper, I have researched on the geochemical character of twenty fourth sediments distributed at research area. The results were as follows. I. The mean size is 3.14ψ at Keum river, 5.72ψ Dongjin river, 5.36 .p 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 sectors has been appeared very positive skewed. N. The kurtosis were very leptokurtic skewed at whole research sector. V. Most elements except CaO, K₂O, CaCO₃, among the character of element chemical composition has a good relation on the size of sediment according to the rariation of contents. Al₂O . Fe₂O₃, MgO, Na₂O, TiO₂, P₂05 etc were increased predominently due to the finness of the size. It showed hish contents K20 at Keum river. Al₂O₃. CaO at Dongjin river Fe₂O5. MgO, Na₂O, P₂O5, CaCO5. Organic etc at Mank.vung 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 Sa, Sr at Keum river Ni, Cr, V, Cu, Pb, Zn at Dongjin, Mankyung river. VB. All elements in the research sector except K₂O, Sa. showed less world mean contents in shallow bottom sediment, however, all elements in coarse sediment are axious to pollularize to the specities minerals.
