Project details
This project focuses on determining the 3D geometry and kinematics of the major crustal element of economic interest within the Musgrave Block - the mafic Giles Complex, host to the Nebo & Babel Ni-Cu-Co deposits. It will allow us to decipher overprinting relationships on a regional-scale, and work towards determining the sequence of crustal movement events and how these events relate to lithospheric setting of the Ni mineralization within layered mafic intrusive complexes.
Three specific questions will be focused on:
• What are the geometry, distribution, and overprinting relationships (relative timing) of major faults and shear zones?
• Can architectural elements be related to episodes of crustal growth? If so, how did these structures behave during crustal growth periods, and do they constrain growth processes?
• What was the influence of architectural elements during major episodes of mineralisation and can these be related to the tectonic setting?
