This dataset provides rheometric data of PDMS Korasilon® Fluids M used for analogue modelling at the Laboratory for Experimental Tectonics at GFZ Helmholtz Centre for Geosciences, Potsdam, Germany.
The material samples have been analyzed at the Laboratory for Experimental Tectonics at GFZ Helmholtz Centre for Geosciences, Potsdam (HelTec) using an Anton Paar Physica MCR 301 rheometer in a plate-plate configuration at room temperature (21˚C). Rotational (controlled shear rate) tests with shear rates varying from 10-4 to 1 s-1 were performed.
According to our rheometric analysis, the material is Newtonian (n = 1) at strain rates below 1 s-1. The viscosities range from 10 to 2000 Pa s.

The data presented here are derived by rheometric testing using an Anton Paar Physica MCR 301 at the Laboratory for Experimental Tectonics at GFZ Helmholtz Centre for Geosciences, Potsdam (HelTec). We used a riffled plate-plate configuration (PP25/P2) with a 1 mm gap. Tests were performed at 21°C.

Samples have been carefully prepared by the same person to obtain a homogeneous mixture and measured consistently following a consistent test protocol. After the introduction of the material into the measuring gap, the sample is allowed to relax for 360 s to remove residual stresses. Rotational tests with controlled shear rate (CSR tests) were performed at 19 different shear rates varying logarithmically from 10-4 to 10-1 s-1 and with respective interval lengths from 1000 to 10 s. Each sample was measured in triplicates to verify reproducibility and test intrinsic variability.
