Abstract

The Paroo Fault is a prospective conduit for the oreforming fluids that created the Mt Isa copper deposit, but its kinematic history and relationship to copper mineralisation are unclear. Fluid inclusion planes in quartz from the fault zone occur in two prominent sets; one set dips more steeply, and the other set less steeply than the fault zone. They may indicate reverse and normal movements, which can potentially be timed with respect to ore-forming fluids. Different rock types within the fault and the different orientations of fluid inclusion planes are evidence of a complex history on the Paroo Fault, which may be the key to copper mineralisation.
