Data for "petro-mineralogical controls on seismic attenuation in volcanic rock samples"
Listed in Teesside University Research Data Repository
Here we include the initial dataset acquired to develop the study presented in the article “Petro-mineralogical controls on seismic attenuation in volcanic rock samples” File ‘Data’ = Petrophysical properties of 25 core samples of volcanic rocks from cored boreholes on The Big Island of Hawai’i.
Description
Folder ‘Waveforms’= Folder 'raw': seismic ultrasonic waveforms recorded on each sample. Time in seconds and amplitude in voltage.
Acquired using shear-type transducers with a piezoelectric crystal of 13 mm and a characteristic frequency of 1 MHz. The pulse repetition frequency was set at 100 Hz and the pulser voltage at 400 V using an ultrasonic square wave pulser/receiver unit (Olympus 5077PR). Folder 'Filtered': seismograms filtered (Butterworth bandpass between 20-800 kHz) used to compute Qc.

Folder ‘Optical Images’= optical images under plane polarised light. The samples were imaged using a Zeiss Axio Imager M2m optical imaging system, with a magnification of 2.5x. Folder ‘uCT’= 2D slice images generated from the micro-CT scanner (Versa XRM 500 from Zeiss-XRadia) with a resolution of 4.2527 μm for the sample 1H, and 22 μm for samples 9H, 11H, 14H and 18H..
