This dataset contains high-pressure ultrasonic measurements on a foliated granitoid core from Well 16B(78)-32 at the Utah FORGE site. Ultrasonic P-waves and two orthogonal S-waves were measured concurrently parallel and perpendicular to the rock fabric. All measurements were made at 150C, at confining pressures between 10 and 70 MPa, and with max/min stress ratios between 1-2. Results indicate that anisotropy is primarily controlled by microfractures, with some residual fabric influence at high stress. Data include raw ultrasonic waveforms, velocity measurements, stress-strain records, and a summary presentation of anisotropy trends and Thomsen parameters.
