Abstract:
The Mt Kitty prospect resides in the heavily structured southern Amadeus Basin approximately 220 km southwest of Alice Springs in Northern Territory Exploration Permit EP-125. The initiation of the Amadeus Basin in this area probably coincided with the onset of Mesoproterozoic rifting, which was associated with the Giles Event (1 080- 1040 Ma) and may have centred on the Musgrave Province which marks the southern margin of the basin. A number of the resultant northwest-trending faults were reactivated at this time. This process defined the shape of the basin and location of basement highs. Renewed rifting, related to continued northeast-directed extension, occurred at the commencement of the Neoproterozoic (800-840 Ma) and ultimately led to the breakup of the Rodinia Supercontinent along the Tasman line. Faults defining the basement fabric were intermittently rejuvenated during later rifting and orogenesis through to the Palaeozoic.
