Abstract

The Seosan Geomenyeo(black submerged rocks), once located at the Cheonsuman bay of Buseokmyeon in Seosan, Korea, is a reef rock now exposed on the land surface. The Geomenyeo can also be found in the ancient geographic maps around the area. The local geographic names, like Buseok and Buseoksa temple are derived from the Geomenyeo. It is composed of ultramafic rocks complex and intrusive felsic igneous rocks. These rocks show diverse facies with various petrographic characteristics caused by geological processes such as intrusion and alteration. Ultramafic rocks complex can be roughly categorized as coarse grained ultramafic rocks and medium grained mafic rocks. Both cases are composed of pyroxene and amphibole, showing the general rock facies of pyroxenite, diabase and lamprophyre. Felsic igneous rocks includes pinkish medium grained granite, porphyritic amphibole granite and aplite with varied mineral compositions. The Geomenyeo is the only ultramafic rocks complex in the Cheonsuman Bay; moreover, it has a distinctive geological and scenic value, as well as a symbolic property. In order to preserve the Geomenyeo, it is necessary to investigate and promote it as a designated heritage site through academic studies, and compensate for the convenience and protection facilities. Additionally, the Geomenyeo should be evaluated as a maritime heritage site, due to the unique local culture as it succeeds the recognition of forefathers which regarded it as a local scenic site with significance.

서산 검은여는 충남 서산시 부석면의 천수만에 있던 암초로, 현재는 육지에 노출되어 있다. 이 일대의 고지도에는 검은여가 표기되어 있으며, 지역의 명칭인 부석과 부석사가 여기에서 유래되었다고 한다. 검은여를 구성하는 암석은 초염기성암복합체와 이를 관입한 규장질화성암류이다. 이들은 위치에 따라 다양한 산출상태를 보이며 관입과 변질 등의 지질학적 작용을 받은 여러 특징들이 관찰된다. 초염기성암복합체는 크게 조립질 초염기성암과 중립질 염기성암으로 구분할 수 있다. 두 암석 모두 휘석과 각섬석으로 구성되어 있으며, 전반적으로 휘석암, 휘록암 및 황반암의 암상을 보인다. 규장질화성암은 담홍색중립질화강암, 반정질각섬석화강암 및 반화강암 등이며, 광물조성은 암석에 따라 차이가 있다. 검은여는 천수만 일대의 유일한 초염기성암복합체로 지질학적 및 경관적 차별성과 상징성이 충분하여 잠재가치가 뛰어난 것으로 판단하였다. 따라서 이를 보존하기 위한 학술적 연구와 편의 및 보호시설 등에 대한 보완을 통해 지정문화재로의 검토와 추진이 필요하다. 또한 검은여를 지역의 명소로 생각하던 선조들의 인식을 현대적으로 계승한다는 점에서 독특한 지방문화를 간직한 해양유산으로 평가되어야 할 것이다.
