초록

연구 목적은 미생물기원으로 추측되는 나선형구조물과 협막구조물에 형성된 침철석과 레피도크로사이트의 광물화작용, 그리고 철수산화물 중에 함유된 중금속함량의 특성을 해석하고자 하였다. 오염된 지하수와 비오염된 지하수의 Cl과 Br의 함량 그리고 Cl/Br의 비율을 이용하여 본 지하수의 오염 정도를 비교해본 결과 인간 활동에 의하여 오염이 진행된 것으로 나타났다. 황갈색 철수산화물을 구성하는 주성분은 $Fe_2O_3$와 $SiO_2$로 나타났다. $Fe_2O_3$ 함량은 58.57wt.%에서 75.73 wt.% 범위이고, $SiO_2$ 함량은 5.8 wt.%에서 16.17 wt.% 범위로 나타났다. 황갈색 철수산화물에 고 함량으로 함유된 중금속원소는 Zn(최대 6,160 mg/kg), Pb(최대 377 mg/kg), U(최대 503 mg/kg), Cr(최대 203 mg/kg) Cu(최대 77 mg/kg), V(최대 162 mg/kg) 및 Ni(최대 105 mg/kg) 등이다. 래스상과 엽편상의 결정들 그리고 침상의 결정들이 나선형구조물과 협막구조물에 발달 돤 것이 관찰되었다. 황갈색 철수산화물에 대한 x-선 회절분석에서 침철석, 석고 및 레피도크로사이트가 관찰되었다.

The objectives of this study are to investigate the biomineralization of goethite and lepidocrocite formed on the twisted-stalk and the sheathed-filament structure that is suggest microbe origin, and heavy metal in the yellow Fe-hydroxide. On the ratio of Cl and the Cl/Br ratios that are a pollution and non-pollution of groundwaters, it is indicated that the groundwater in this areas were relatively contaminated by human activity. The composition of the yellow Fe-hydroxide consisted mainly of $Fe_2O_3$ and $SiO_2$. The content of $Fe_2O_3$ ranges from 58.57 wt.% to 75.7 3wt.%, and $SiO_2$ content ranges from 5.8 wt.% to 16.17 wt.%. Heavy metal elements such as Zn(max. 6,160 mg/kg), Pb(max. 377 mg/kg), U(max. 503 mg/kg), Cr(max. 203 mg/kg), Cu(max. 77 mg/kg), V(max. 162 mg/kg), Ni(max. 105 mg/kg) were observed to be rich in those yellow Fe-hydroxide. The lath and platy crystals and needle-shaped crystals were clearly observed on the twisted-stalks and sheathed-filaments structure. The goethite, gypsum, and lepidocrocite were identified in the yellow Fe-hydroxide by x-ray powder diffraction.
