Journal of Geophysical Research - Solid Earth Title: The impact of rheology on the transition from stick-slip to creep in a semi-brittle analog Authors: Thomas Birren and Jacqueline E. Reber Affiliation: Department of Geological and Atmospheric Sciences, Iowa State University, Ames, IA 50011 DataShare: Iowa State Univerity's Open Research Data Repository Description of data: "1 wt percent.zip": contains set of force and displacement data for 1 wt.% Carbopol trials. "exp26.csv" is taken as representative. "2 wt percent.zip": contains set of force and displacement data for 2 wt.% Carbopol trials. "exp22.csv" is taken as representative. "3 wt percent.zip": contains set of force and displacement data for 3 wt.% Carbopol trials. "exp24.csv" is taken as representative. Folder "Benchmark Tests": contains set of force and displacement data for empty apparatus trials. By column: Time (seconds), Displacement (cm), Pulling force (N). "exp22 PIV.zip", "exp24 PIV mat files", "exp26 PIV mat files": contains particle image velocimetry matfiles output from the PIVlab application in Matlab. They include a length and velocity scaling factor with units given. Additionally, they include horizontal, u, and vertical, v, velocity in units given in the scaling factor. The x and y coordinates are the positions of the horizontal and vertical velocity components analyzed. "Exp 22.zip": contains photos from 2 wt.% representative experiment. Time step between photos: 2 seconds Scaling: 2.1917e-04 m/px "Exp 24.zip": contains photos from 3 wt.% representative experiment. Time step between photos: 2 seconds Scaling: 1.7e-03 m/px "Exp 26.zip": contains photos from 1 wt.% representative experiment. Time step between photos: 2 seconds Scaling: 1.8e-03 m/px "Rheometer.zip": Presented in the Supplementary Information are Carbopol rheology measurements. I've inlcuded .csv files detailing the rheology measurements we made. The .txt files are titled 'carb_1_6-1-18.csv.' The first '1' represents the weight percent of the Carbopol solution and the rest of the title is the date the sample was measured. The .csv file contains 6 columns: Time in seconds, Shear Rate in per seconds, Shear Stress in Pascals, RPMs, Viscosity in Pascal seconds, and Torque in percent.
