Short summary
This study investigates one of the key processes that may lead to the destruction and destabilization of continental tectonic plates: the infiltration of buoyant, hot, molten rock (magma) into the base of the plate. Using simple calculations, I suggest that heating during melt–rock interaction may thermally perturb the tectonic plate, weakening it and potentially allowing it to be reshaped from beneath. Geochemical, petrologic, and geologic observations are used to guide model parameters.
