WebAn experimentally established relationship enables the conversion of compressional seismic velocity to heat production (A). The conversion, performed for 47 characteristic seismic sections from various tectonic units in Central and Eastern Europe, yields a general decrease of A with depth (z). The pattern of decrease depends on geological age: young … Web1 jan. 2014 · Lastly, on the basis of velocity data, the three-dimensional lithosphere density distribution of Asian lithosphere is determined by using Algebra Reconstruction … rea and tootsie

Along the rift axis, Moho rises under the troughs and deepens under inter-trough zones. Moho also deepens northwards, consistent with the northward propagation of the Red Sea Rift ( Figure 3 a).
