Giant Radial Dike Swarms

Session ID#: 25643

Session Description:
Giant radial dike swarms are known from Earth, Mars and Venus and may form in response to mantle plume driven uplift and fracturing of planetary lithospheres. Giant radial dike swarms manifest an episodic but important mechanism for heat transfer from the deep mantle to planetary surfaces. On Earth, their emplacement may trigger plate reorganization, triple junction formation, ocean basin opening and rapid environmental change. This session seeks theoretical and observational contributions concerning the tectonics, geochemistry, timescales and possible environmental implications of the emplacement of giant radial dike swarms, ranging from understanding melt generation in the source region through to magma-lithosphere interactions.
