3-DIMENSIONAL DEEP TEMPERATURE MODELING ALONG THE EUROPEAN GEOTRAVERSE

Lithospheric temperature distributions, Moho heat flow and the thermal thickness of the lithosphere along the European geotraverse were nume rically calculated for a simple 3-D geothermal model. Relatively low c rustal temperatures dominate the Baltic shield (T-M 400-500 degrees C) , while high Moho temperatures of up to 900-1000 degrees C are to be e xpected in. the Alpine-Mediterranean area. Also the expected heat flow from below the crust may vary from less than 20 mW m(-2) in northern Europe, to over 50-60 mW m(-2) in the south. The results for two diffe rent approaches to assess the lithospheric temperature field are given , compared and discussed in terms of the data reliability.
