Comparison of seismic traces, lithology, conductivity from drillholes logs, conventional unconstrained MT inversion and texture guided cooperative inversion outcomes, along the trace of drill hole 1. The prior model conductivity for unconstrained and texture guided cooperative inversion is shown in the right hand panel. Immediately to the left of curves for the prior model we present the final unconstrained and texture guided cooperative inversion outcomes. We observe that the texture guided cooperative inversion, which is run on a Cray Cascade XC40 Super Computer, has significantly changed the conductivity range but retained the general geometry of cover and basement inherited from the Seismic Texture distribution. The final cooperative inversion RMS misfit of 1.3. This is exceedingly small. Lithology abbreviations are: QAL Tertiary volcaniclastics, tuffs and siltstones. TG Rhyodacite volcanics Tuffaceous silt and clay. TS Tuffaceous silt and clay. TV Green glassy volcanics. SBMT Siliceous mudstone with tuff. BMT Mudstone with tuff. QTZT Quartzite. BAS Basalt. TUFF Tuff. Note that Fig. 11 is presented in a similar format to that shown in Le, et al.²⁴ so that comparison to alternative inversion strategies can be made.
