A new report showcasing recent 3D inversion modelling of the complete Cloncurry magnetotelluric dataset has just been released. This work, spearheaded by GSQ geophysicist Janelle Simpson, contains a suite of inversion models and detailed writeup of the thoughts behind the models and the modelling results achieved. There is also a model package containing several different formats to help people interrogate the model suite for themselves.
Results of modelling show several strong conductors in the modelling area coalescing into a large mid-crustal conductor. Some of the identified conductors are associated with major faults, while others are discrete upper crustal conductors potentially of interest to exploration companies. Figure 1 shows results from one of the inversion models. The report and model package can be found here. https://geoscience.data.qld.gov.au/data/report/cr135059
