Geometry and growth of sill complexes: insights using 3D seismic from the North Rockall Trough

岩床

在地质学中，岩床（sill）是一种侵入在更老沉积岩层、火山熔岩或凝灰岩层之间，或沿变质岩叶理方向侵入的板状侵入体。“岩床”是一种整合型侵入岩层，意味着岩床不会穿过原先已存在的岩层。在高岩浆通量情况下，岩床的堆积将构建成一座岩床复合体和大型岩浆房。相较之下，岩脉则是一种穿过了更古老岩石的非整合型侵入岩板。岩床由岩脉供给岩浆，除非在特殊位置，它…

Sill (geology)

In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of…
