초록
梁山斷層은 韓半島 南東部 寧海에서 洛東江 河口에 이르는 斷層이다. 이 斷層을 沿하여 扇狀地 起源의 河成段丘가 연속적으로 형성되어 있으며, 高位面, 中位面, 종低位面으로 구분된다. Mindel/Riss 間 期 혹은 그 이전에 형성되었을 것으로 추정되는 高位面은 斷片的으로 분포하고 있고, Riss 期 및 最終氷期 중에 각각 형성된 것으로 추정되는 中位面 및 低位面은 넓은 지역에 걸쳐 분포한다. 梁山斷層 주변의 地形
Yangsan Fault stretches from Yonghae to the mouth of Naktong River in the south-eastern part of Korean Peninsula. The river terraces originated from alluvial fans are classified into the High, Middle, and Low Surfaces. The High Surfaces which were distributed in fragments are considered to be formed during the Mindel/Riss Interglacial period or the former periods. But the Middle and Low Surfaces which were distributed widely are considered to be formed during the Riss and Last Glacial period respecitively. The geomorphic and geologic features around Yangsan Fault suggest that the fault is right strike-slip fault, and some geomorphic evidences of active fault were found on Eonyang and Sinkwang Basin.
