Mount Isa Seismic Workshop, June 2008
Specific Scientific Objectives:
• Acquire series of E-W and N-S transects to image crustal architecture of Western and Eastern Successions and adjacent undercover areas
• Integrate seismic with potential field and geological datasets to constrain 3D and 4D models for the Mount Isa Inlier
• Determine depth, geometry & distribution of pre-1800 Ma basement
• Capture deep-tapping faults & low-angle detachments• Determine extent & geometry of basin inversion• Determine structural & crustal setting of
mineralisation– Zn-Pb-Ag– Au, Cu (IOCG)
Mount Isa Seismic Workshop, June 2008
Getting down to business: capturing basin & crustal architecture in seismic reflection images
What gets imaged:• Moho• Non-vertical faults & shear
zones (incl. detachments)• Basement topography• Unconformity-bounded
