Fault-segment rupture, aftershock-zone fluid flow, and mineralization
We propose that zones of transient high permeability around ancient fault systems can be predicted if fault segments and likely locations for paleo-rupture arrest are identified. Lode gold deposits in the Kalgoorlie terrane, Western Australia, are the products of focused fluid flow through faulted crust. Deposits in the Mount Pleasant area are clustered on small-displacement structures over ∼10 km of the >50-km-long Black Flag fault. Field relationships and net slip distribution along the fault...[Show more]
