To study biogeochemical characteristics and origin organic matter, sediment samples were taken from Site of 1249C and Stie 1251B of ODP Leg 204. Data of Rock-Eval, isotope, and element analysis generally indicate dominance of marine organic matter in sediments deposited under marine sedimentary envi...

가스 하이드레이트가 주로 매장된 곳은? | , 1996). 가스 하이드레이트는 심해저와 영구동토(Permafrost) 지역에 광범위하게 분포하고 있으며 가스 하이드레이트가 해리되면서 전 지구적인 기후 변화 및 해저면 불안정 요인으로 작용하는 것으로 알려지면서 관련 연구가 다양하게 진행되고 있다(Shipley and Didyk, 1982; Paull et al., 1996; Katz et al. | |
가스 하이드레이트란 무엇인가? | 가스 하이드레이트(natural gas hydrate)는 저온, 고압 조건 하에서 천연가스가 수소결합을 하는 물분자의 격자 안에서 포획되어 형성된 얼음과 비슷한 형태를 보이는 고체상 화합물(solid compound)이다(Paull et al., 1996). | |
열분석 결과 해석은 다양한 지화학적 결과를 종합해서 고려해야 하는 이유는 무엇인가? | 분석결과 Site 1249C와 Site 1251B의 유기물은 해양기원 유기물이 우세하며 이러한 결과는 퇴적물의 퇴적당시 환경이 일반적인 해양 환경이었음을 시사한다. 그러나 Rock-Eval 열분석 결과는 다른 분석결과와 반대의 결과를 나타내는데 이러한 결과는 열적으로 미성숙한 유기물이 열분석 과정에서 유기물의 특성이 제대로 반영되지 못하기 때문이다. 따라서 열분석 결과 해석은 다양한 지화학적 결과를 종합하여 해석할 필요가 있다. |
