Descriptions
This dataset provides friction data from ring-shear tests (RST) for mixtures of quartz sand and sili-cate cenospheres, which are used for analog experiments in the laboratory of the Institute of Geo-physics of the Czech Academy of Science (IG CAS) (Warsitzka et al., 2021). The mixtures have been characterized by means of internal friction coefficients µ and cohesion C as a remote service by the Helmholtz Laboratory for Tectonic Modelling (HelTec) at the GFZ German Research Centre for Geosciences in Potsdam. According to our analysis the materials show a Mohr-Coulomb behaviour characterized by a linear failure envelope. Peak friction coefficients µP of the tested materials range between 0.55 and 0.75, dynamic friction coefficients µD between 0.47 and 0.60 and reactivation friction coefficients µR be-tween 0.52 and 0.65. Cohesions of the materials vary between 20 and 120 Pa. The materials show a minor rate-weakening of <1.2% per ten-fold change in shear velocity v.
