Abstract

We investigated geochemical characteristics of the Dodong Basaltic Rocks in the lower part of the Ulleung Island. They have lithological range of alkali basalt to trachybasalt, belonging to Na and K subseries of alkaline series. They mostly fall within the field of alkalline within-plate basalts on tectonic discrimination diagrams, and then plot in the field of oceanic island basalt (OIB). Geochemically, extension of lithospheric mantle and asthenospheric upwelling after East Sea under an Cenozoic extensional tectonic setting might be a heat source for partial melting of the enriched lithospheric mantle, which might generate the basaltic magma. But we cannot exclude that mantle plume might also be a heat source for melting of the lithospheric mantle.

울릉도의 하부에 분포하는 도동현무암질암류에 대해 지구화학적 특징을 고찰하였다. 이 현무암질암류는 알칼리 현무암-조면현무암의 암질 범위를 가지며 알칼리 계열의 Na 계열과 K 계열에 거의 대등하게 도시된다. 미량원소(Zr, Nb, Y)를 이용한 현무암류의 생성 조구조환경 판별도에서, 이들은 판내 알칼리 현무암의 범주에 도시되고 해양도 현무암의 영역에 속한다. 지구화학적으로 울릉도는 동해생성 후에 동반된 암석권 맨틀의 신장 및 연약권 용승이 열원이 되어 부화된 암석권 맨틀의 부분용융을 초래하여 도동현무암질 마그마가 생성된 것으로 추론된다. 한편 맨틀 플륨이 암석권 맨틀 용융의 열원이 되었다는 것도 배제할 수 없다.
