Inactive plate margin
WebA passive continental margin is one in which continent and adjacent ocean basin resides on the same tectonic plate. Passive continental margins are developed on both sides of a divergent plate boundary as a result of rifting as indicated in Fig. 5.4B. The absence of a plate boundary at the continental margin implies that the continent moves in ...

WebIntracontinental basins are large areal depressions that are tectonically inactive and not near any plate boundaries. [2] Multiple hypotheses have been introduced to explain this slow, long-lived subsidence: [2] long-term cooling since the breakup of Pangea, interaction of deformation around the edge of the basin and deep earth dynamics. WebIntra-plate volcanism occurs when rifting of the plate occurs. But you don't necessarily need a hotspot (or rather a mantle plume) to trigger a rifting process. There are two types of rifting: Active rifting, which indeed implies the rise of a mantle plume under the lithosphere. This yields to the bulging of the lithosphere, then to its extension.

WebBecause the edges of the continents on opposite sides of the divergent boundary are considered tectonically inactive, they are called passive continental margins.
