Structural controls on fluid movement during deformation and mineralisation at the Porgera gold deposit, Papua New Guinea
The Porgera gold mine is a large, high-grade, vein and fault-hosted deposit located in the highlands of Papua New Guinea. Gold mineralisation at Porgera is spatially associated with oxidised, hydrous magmas of the Porgera Intrusive Complex. Prior to emplacement of the intrusive complex, the Porgera area experienced a period of shortening due to collision of a southward-moving arc with the northern edge of Papua New Guinea. Two stages of mineralisation which have distinct mineral...[Show more]
