(2017), who used empirical methods to determine material properties and find a friction angle of ca. 57˚ (i.e. a friction coefficient of ca. 1.5).

Abstract

This dataset provides internal data from ring-shear tests (RST) on a feldspar sand material that has been used in tectonic experiments by among others Montanari et al. (2017) and Zwaan et al. (2020) in the Tectonic Modelling Laboratory of CNR-IGG at the Earth Sciences Department of the University of Florence (Italy) as an analogue for brittle layers in the crust. The material has been characterized by means of internal friction coefficients μ and cohesions C as a remote service by the Helmholtz Laboratory for Tectonic Modelling (HelTec) at the GFZ German Research Centre for Geosciences in Potsdam for the Tectonic Modelling Laboratory of CNR-IGG at the Earth Sciences Department of the University of Florence (CNR-UF) According to our analysis the material behaves as a Mohr-Coulomb material characterized by a linear failure envelope. Internal peak, dynamic and reactivation friction coefficients are μP= 0.72, μD= 0.67, and μR= 0.72 respectively. Internal cohesions C are in the range of 60 to 120 Pa. Note however that these values differ from those reported by Montanari et al. (2017), who used empirical methods to determine material properties and find a friction angle of ca. 57˚ (i.e. a friction coefficient of ca. 1.5).
