Figure 3From: Physical property relationships of the Rotokawa Andesite, a significant geothermal reservoir rock in the Taupo Volcanic Zone, New ZealandLoading frame set-up for acquisition of elastic velocities at the University of Canterbury. The frame is a Tecnotest 3,000 kN loading frame and a stress of 10Â MPa was applied to each sample cycle to ensure a consistent waveform and quality picking of the first arrival time of the acoustic pulses (note that the figure is not to scale).Back to article page
