Title

Data (ultrasonic, mechanical) and microstructures of shear failure in Lanhelin granite under upper crustal conditions (NERC Grant NE/M004716/1)

Abstract

Data has been recorded during triaxial rock deformation experiments where Lanhelin granite samples were subjected to dynamic and half-controlled shear failure. The data consists of mechanical data (load, displacement, confining pressure, strain gauge data), ultrasonic data (AE source locations and arrival times, sensor locations, arrival times of active acoustic surveys), and scanning electron microscope images of the samples after shear failure. Dataset contains all data necessary to evaluate the results presented in the paper entitled: 'Off-fault damage characterisation during and after experimental quasi-static and dynamic rupture in crystal rock from laboratory P-wave tomography and microstructures' by Aben, Brantut, and Mitchell, Journal of Geophysical Research: Solid Earth.

Quality and validity

Lineage

Triaxial experimental loading apparatus (rock physics laboratory, department of earth sciences, University College London) equipped with displacement sensors, pressure transducer, and load cell. In situ ultrasonic measurements were performed during rock deformation by 16 in-house manufactured PZT transducers, connected to a pulser-amplifier and digital oscilloscopes. Post-mortem thin sections were studied by SEM at UCL's Earth Sciences department. Further methodology: See manuscript entitled 'Off-fault damage characterisation during and after experimental quasi-static and dynamic rupture in crystal rock from laboratory P-wave tomography and microstructures' by Aben, Brantut, and Mitchell, Journal of Geophysical Research: Solid Earth.
