This study aims to investigate electrical resistivity anomalies and structural features in the Curnamona Province.
Conducted a comprehensive multi-geophysical investigation over a 15 x 15 km area using magnetotellurics and passive seismic methods.
Performed ambient noise tomography and H/V spectral ratio analysis at 143 sites and 102 sites respectively.
Used fuzzy c-mean clustering to analyze 3D resistivity and shear-wave velocity models.
Identified a conductor <1 Ω⋅m at depths >1.5 km in basement rock, suggesting structural control by a basement fault.
Estimated cover depths ranging from <30 m to up to 100 m across the region, providing insights into sediment thickness.
Proposed that the conductor is likely due to graphite in metasedimentary rocks with low resistivity.
