Integration of Stress–Strain Maps in Mineral Systems Targeting for IOCG Mineralisation within the Mt. Woods Inlier, Gawler Craton, South Australia

The application of finite element analysis is used to simulate the relative distribution and magnitude stress–strain conditions during a geologically brief, NNW-SSE-oriented, extensional event (1595 Ma 1590 Ma), co-incident with IOCG-hydrothermal fluid flow mineralisation across Mt Woods Inlier, Gawler Craton, South Australia. Differential stress shear strain maps modelled terrane highlight regions that were predisposed localization, failure throughput simulated event. These are integrated other datasets interpretation layers, one which proposed structural–geometrical relationship apparent in many world-class IOCG deposits, including Prominent Hill, Olympic Dam, Sossego, Salobo, Cristalino Candelaria. deposits occur at steeply plunging, pipe-like intersections conjugate systems faults, shears and/or contacts, wherein obtuse angle may have been bisected by maximum principal axis (viz., σ3) mineralisation. Several layers also for generation targets, such as distance from major zones, favourable host lithologies, proximity tectonostratigraphic contacts markedly contrasting competency. result an target index or heat map prospectively Mt.
