Abstract

The investigation of the Earth's crust and upper mantle by seismic reflection methods has significant history in Hungary. In the bulk of sections published in other countries the upper mantle seems to be transparent. In the present paper investigations are discussed which lead to the conclusion that this apparent transparency is due to the frequency range below 10 Hz being neglected in both signal generation and observation in the overwhelming part of deep reflection soundings carried out on continents. The correctness of the assumption that arrivals from the time range of the asthenosphere are primary reflections is subjected to further investigation and conclusions are made concerning the structure of the asthenosphere. -from Authors
