WebConstructive plate boundaries or margins are regions where new oceanic crust is being generated. However, in order for the magma to ascend to the surface and build new lithosphere, the earlier formed crust must be pulled apart and fractured to create a new magma pathway. 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.
