(4) . . Oxygen and Hydrogen Isotopic Compositions of Stream Waters in the Han River Basin Kim-Kyu Han*, Lee-Sae Hee Department of Science Education, Ewha Womans University, Seoul 120-750 Korea Oxygen and hydrogen isotopic compositions of stream water in the Han river basin are expressed by the equation of δD=6.6δ18O-7.4, which is not satisfy the meteoric water line (δD=8δ18O+10). It might be depended on the local climatic condition and the evaporation effect in the Han river basin. The δ18O and δD values of stream water in the Han river basin range from −8.2 to −10 (avg. −9.1 ) and −60 to −96 (avg. −69 ), respectively. The δD= −66~ −96 , avg. −69 ) is slightly stream water from the South Han river (δ18O= −8.9~ −10 , avg. −9.3 more depleted in 18O and D than those of North Han river ( 18O= −8.4~ −9.7 , avg. −9.2 , δD= −64~ −95 , avg. −69 ). It reflects more altitude effect than the effect of latitude and inflow of the 18O enriched SO42− and HCO3− from the carbonate rock and sulfide minerals in the Taebagsan and Hwanggangri mineralized zone. The Main 18 O= −8.2~ −10 (avg. 9.0 ) is stream water of the Han river having δD= −60~ −76 (avg. −68 ) and 18 enriched in O compared to the South and North Han river waters, which is caused by the evaporation effect. Binary simple mixing ratio of the Main Han river water between South and North Han river waters was obtained to be 6 : 4 by the isotopic data, suggesting a strong influence of South Han river water to the Main Han river water.. . . . . . . . . . . . . . . . . oxygen and hydrogen isotopic compositions, stream water, Han river basin, altitude effect, evaporation effect..
