Application to Greenland
Predicted geothermal geothermal heat flux in Greenland.
Values in black boxes – heat flux measured in boreholes and in
hydrothermal complexes (see references in Rysgaard et al., 2018). Color-
coded circles with numbers – calculated values for each station, used in
interpolation. Dotted lines – various hypotheses for the Iceland hotspot.
Lithosphere thermal thickness,
assuming the lithosphere thickness at reference stations is 200 km
(Model 1, NUK) and 150 km (Model 2, ANG and SOE). Thin lithosphere
(< 70 km) cannot be determined, and stations with AET > 1.3 km are
assigned the zLAB values of 50–80 km proportionally to the AET values.
Model 1 adopts the Moho-equivalent topography relationship based on global averages for the continental Moho depth (41.1 km) and typical densities of
the continental crust (2.8 t/m3) and in situ upper mantle (3.35 t/m3).
Model 2 is constrained by regional correlation between the seismic Moho depth and the equivalent topography for Greenland, which yields the same
density contrast across the Moho as in Model 1 and the average Moho depth of 37.5 km.
