Seismic Wave AttenuationM. N. Toksöz, David H. Johnston Society of Exploration Geophysicists, 1981 - 459 Seiten "We have undertaken the editing of this volume to help the broad-range research effort gain a better understanding of attenuation and its applications to seismic exploration problems... We have emphasized the material most relevant to exploration geophysics. As a result, most of the papers compiled here deal with sedimentary rocks, the effects of fluids, and the pressure ranges encountered in shalow crustal layers."--Preface. |
