The shallow sediments in the southwestern Ulleung Basin consist of mass flow deposits such as slide/slump and debris flow deposits (DFD), caused by slope failure. These sediments are proven to be important in studying geological disaster and stability of the seafloor. In this paper, we analysised th...

대규모의 사면붕괴 및 질량류가 야기하는 것은? | 대규모의 사면붕괴 및 질량류는 쓰나미(Tsunami)와 같은 지질재해를 유발하여 인명 및 재산피해를 입힐 수 있을 뿐만 아니라 원유시추시설이나 해저송유관 등의 해저시설물에 직접적인 손상을 야기한다. 남아프리카 아굴하즈와 파푸아뉴기니에서 발생한 해저사태는 많은 피해를 발생시킨 재해로 기록되었다(Dingle, 1977; Yoshiaka et al. | |
질량류 퇴적체는 무엇에 의해 주로 발생되는가? | 질량류는 천부 퇴적물을 심해저로 운반하여 퇴적분지를 채우는 해양 퇴적환경의 중요한 메커니즘 중 하나이다. 일반적으로 질량류 퇴적체는 대륙붕단이나 협곡의 상부에 축적된 불안정한 상태의 퇴적체가 무너져 하부로 흐르는 사면붕괴(Slope failure)에 의해 주로 발생되며 다양한 중력구동 작용에 따른 대량의 퇴적물 이동으로 야기된다(Bonnie et al., 1979). | |
쇄설류 퇴적체에 대한 연구가 지질재해 및 해저면의 안정성을 연구하는 측면에서 중요한 의미를 갖는 이유는? | 동해 울릉분지 남서부의 천부퇴적층은 대부분 사면사태와 쇄설류 퇴적체로 구성되어 있으며 주로 사면붕괴에 의해 야기된다. 따라서 쇄설류 퇴적체에 대한 연구는 지질재해 및 해저면의 안정성을 연구하는 측면에서 중요한 의미를 갖는다. |
