摘要: Seismic wave propagation in geological formations is altered by the presence of clay minerals. Knowledge about elastic properties therefore essential for interpretation and modeling seismic response clay-bearing formations. However, due to layered structure clay, it very difficult investigate its properties. We measured using atomic force acoustic microscopy (AFAM). The forces applied during experiments were not higher than 50 nN. adhesion from pull-off included into our calculations means Derjaguin-Mueller-Toporov model contact mechanics. obtained values modulus varied 10 17 GPa depending on various parameters that describe dynamics a vibrating beam
