Web1 apr. 2024 · Note, however, that due to the age of the plume-lithosphere interaction (about 50–100 Ma for Greenland [Martos et al., 2024], and 100–130 Ma for Africa [Celli et al., 2024]), the heat flux anomaly in Greenland is likely still increasing, while the heat flux anomaly in Africa should be approximately at its maximum value or already decreasing.

Web1 jan. 2014 · Heat flow from the continental crust or lithosphere, which are those portions of the plates that are not directly formed by seafloor spreading at mid-ocean ridges and are not generally subducted. Introduction Heat flow is a fundamental property of the Earth. Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe…
