Abstract

The XRF core scanner was used, to analyze high resolution chemical elements in deep sea sediment cores from Clarion-Clipperton fracture zone of the northeastern Pacific. Comparison of data estimated by the XRF core scanner with ICP-AES showed relatively weak correlation coefficients between elements (especially Ba, Pb, Sr, Zr) except for Mn contents ($r^2$ > 0.89). However down-core variations of most elements seemed to be well matched each other and furthermore, XRF core scanner data reflected changes of sedimentary facies characterized by sediment colors. Mn/Al ratio dramatically changed at boundaries of facies in BC08-02-05 and BC08-02-13 but progressive changes occured in BC08-02-02, BC08-02-09 and BC08-02-10 where the sediments have been affected by bioturbations. The difference of Mn/Al ratio in each facies (Facies I, Facies II, Facies III) has been caused by redox condition of depositional environment. Vertical change of Mn/Al ratio were divided into two types probably affected by activities of benthic organisms in the study area.

북동태평양 클라리온-클리퍼톤 지역에서 채취된 주상시료 내 원소의 수직적인 변화를 살펴보기 위하여 XRF 코어스캐너를 이용하여 주요원소(Al, Ca, Fe, Mn, Ti, Ba) 및 미량원소(Pb, Sr, V, Zr, Zn)를 2 mm 간격으로 분석하였다. XRF 코어스캐너의 분석 능력을 검증하기 위하여 동일 주상시료에서 부시료를 채취하여 ICP-AES 정량분석을 실시하였다. XRF 코어스캐너와 ICP-AES 측정값의 상관계수는 Mn ($r^2$ > 0.89)을 제외하면 대체적으로 낮다. 그러나 두 측정값의 수직적인 분포형태는 매우 유사하며 퇴적물 색상에 의해 분류된 퇴적상 변화와 거의 일치된다. Mn/Al 비는 각 퇴적상(Facies I, Facies II, Facies III)에서 뚜렷한 차이를 보인다. 그리고 각 퇴적상 경계가 뚜렷한 BC08-02-05와 BC8-02-13에서는 퇴적상에 따른 뚜렷한 Mn/Al 비의 변화가 보이나, 퇴적상 경계가 생물활동으로 점이적인 BC08-02-02, BC08-02-09 그리고 BC08-02-10에서는 점이적인 Mn/Al 비가 나타났다. 각 퇴적상의 원소 함량차이는 퇴적물내 산화-환원 환경 변화에 의해서 조절되며, 원소들의 수직적인 분포형태는 퇴적물내 생물활동에 영향을 받는 것으로 나타났다.
