| Abstract: | Summary. The presence of anisotropy has been established and its parameters have been estimated by the combined use of compressional and shear, SH -and SV -waves. Anisotropy has been studied in argillaceous and carbonate rocks to a depth of 2 km by combined surface and borehole observations along longitudinal and non-longitudinal vertical lines with linear shot lines. Anisotropy in carbonate rocks has been found to be a function of their heterogeneity, ordered fracturing and the amount of clay. The highest anisotropy has been found in argillaceous rocks irrespective of their depth and degree of heterogeneity. |
