High velocity friction experiments of Lisan formation (Dead Sea, Israel) simulated gouges

The dataset in the repository refers to friction measurements of powdered rock samples from the Dead Sea carried out in a low to high velocity rotary shear (LHVR) apparatus (Durham University, UK) in 2014-2015. The dataset comprises rock mechanics data collected during 14 friction experiments performed in a low to high velocity rotary shear (LHVR) apparatus at room temperature, seismic (1.3 m s^-1) slip rates, normal loads ranging from 1-18 MPa and under room-humidity and brine-saturated (drained) conditions. The material tested was obtained from the powdering of the Lisan Formation rock samples (Dead Sea, Israel), containing between 40-60% aragonite (grain size < 15 μm), 30-50% clay (mixed layer illite-smectite and kaolinite), and up to 10% quartz, gypsum and calcite (grain size < 100 μm). The samples used for the laboratory friction experiments performed at Durham University Rock Mechanics laboratory, whose results are included in the data files, were collected during a field campaign in the locality of Masada (Israel) in 2012. The Data Table files contains the source data of 14 friction experiments performed in a rotary shear apparatus, including informations about the samples and experimental conditions (Columns A-G) and the measured relevant parameters as follows: Column A: Experimental code Column B: Date/time Column C: Type of device used for the measuremements Column D: Starting material used during the experiment Column E: Experimental conditions Column F: Measurement time Column G: Sampling rate Column H: Time (s) Column I: Axial Load (kN) Column J: Axial Displacement (mm) Column K: Torque (Nm) Column L: Rotation angle (deg) Column M: Revolution rate (rpm) Column N: Cumulative number of rotations
