Description:
We use regional geology and previously established structural patterns, integrated with aeromagnetic and gravity datasets, to identify a major Neoproterozoic rift basin underlying Pz strata of the eastern Georgina Basin. Aeromagnetic datasets show N-S elongate highs adjacent to a prominent low and separated by a steep gradient that coincides with the Pilgrim Fault, a Mesoproterozoic terrane boundary in the Mt. Isa region that continues southward for at least 180 km as a high-angle dip-slip fault offsetting Pz strata. South from the Mt. Isa region discontinuous, patchy magnetic highs interspersed with magnetic lows merge into NW-trending, linear highs east of the fault trace, while a single, large magnetic low is present west of the fault. First vertical derivative data shows a similar pattern, but emphasizes how the textural definition of the magnetic signature produced by the exposed basement in the Mt. Isa region becomes less defined and broader to the south with increasing sedimentary cover. Gravity data shows broad linear bands roughly parallel to the magnetic signature, but encompassing larger basement blocks.
