Abstract

As results of X-ray diffraction analysis, samples of asbestos and soil were composed maily of dolomite ($CaMg(Co_3)_2$, tremolite ($Ca_2Mg_5Si_{18}O_{22}(OH)_2$), actinolite ($Ca(Mg,\;Fe)_6Si_8O_{22}(OH)_2$), talc ($Mg_3Si_4O_{10}(OH)_2$), calcite ($CaCO_3$) and small amounts of quartz ($SiO_2$) and clay minerals. The average size of asbestos fibers was about $100{\mu}m$ and maximum of some asbestos was $250.0{\mu}m$ in length. The aspect ratio of asbestos fiber were over 3 : 1 and inclined extinction in the range of $8.0-19.5^{\circ}$. Single isolated fragments of asbestos are probably fiber and acicula form in crystal edge along the cleavage plane. Tremolite that composed main asbestos mineral in rock and soil around Dong-a mine is higher content of Fe than actinolite asbestos.

동아광산에서 채취한 암석 시료의 X-선 회절분석 결과 주 구성광물은 백운석(Dolomite : $CaMg(Co_3)_2$, 투각섬석(Tremolite : $Ca_2Mg_5Si_{18}O_{22}(OH)_2$), 활석(Talc : $Mg_3Si_4O_{10}(OH)_2$), 방해석(Calcite : $CaCO_3$)이며, 소량의 석영(Quartz : $SiO_2$)을 포함하고 있다. 편광현미경 관찰 결과 종횡비는 일반적으로 정의하는 3 : 1의 수치보다 높은 값을 나타내며 신장방향에 대한 소광각은 $8.0-19.5^{\circ}$의 범위로 사소광을 나타낸다. 주사전자현미경 관찰 결과 석면의 장경은 $5{\mu}m$ 이상이고 최대 $250{\mu}m$ 정도이며 종횡비는 3 : 1 정도이다. 암석시료에서 나타나는 석면결정은 벽개면을 따라 성장하고 있으며 결정의 끝부분이 침상형태를 나타낸다. 에너지분산분광분석결과 투각섬석이 주 구성광물인 시료는 대체로 Fe의 함량이 높게 나타난다.
