Popis: A new instrument has been developed to measure the compressional attenuation and Young’s modulus of rocks in the seismic‐frequency range. This instrument has been calibrated over a frequency range from 1 mHz to 100 Hz at a strain of about 2.5×10−6. The attenuation of the sample is calculated from a relative phase measurement between a low‐attenuation reference material and the sample. The Young’s modulus of the sample is calculated from the displacement amplitude of the sample relative to the displacement amplitude of the reference material. Use of this instrument has allowed the investigation of the dependence of a rock’s attenuation and Young’s modulus on its fluid content.
