The duplex system has been considered as an important slip-transfer mechanism to evaluate the evolution of orogenic belts. Duplexes are generally found in the hinterland portion of fold-thrust belts and accommodate large amounts of total shortening. Thus, understanding its geometric and kinematic ev...

듀플렉스 시스템은 무엇을 전달하는 매커니즘 가운데 하나인가? | 듀플렉스 시스템(duplex system)은 조산대의 진화에서 슬립을 전달하는 중요한 매커니즘 가운데 하나로 고려되어 왔다. 이들은 일반적으로 습곡-단층대의 후방지(hinterland)에 발달하며, 조산대를 이루는 총 수축의 많은 부분을 수용한다. | |
듀플렉스는 어떻게 나눌 수 있는가? | 지층-평행 수축 벽개(LPS cleavage)와 분리단층습곡(detachement fold) 또한 동일한 역할을 수행할 수 있다. 이러한 견지에서, 듀플렉스는 1) 단층 듀플렉스, 2) 벽개 듀플렉스, 3) 습곡 듀플렉스의 3가지 유형으로 나눌 수 있다. 단층 듀플렉스는 다시 Boyer-type 듀플렉스와 커넥팅-스플레이(connecting splay) 듀플렉스로 세분된다. | |
Boyer-type 듀플렉스는 어떤 형태인가? | 단층 듀플렉스는 다시 Boyer-type 듀플렉스와 커넥팅-스플레이(connecting splay) 듀플렉스로 세분된다. 전자는 1980년대에 트러스트시스템의 개념을 적용하여 최초로 정의된 듀플렉스 형태이고, 후자는 듀플렉스 형성 시 포로암들의 발달 순서에 있어 전자의 듀플렉스와 차이를 가진다. 이들 단층 듀플렉스 유형은 전 세계적으로 주요 습곡-단층대의 구조진화 연구에 널리 적용되어왔다. |
