Metallogeny of Oceanic-Type Crust of marginal basins behind some subduction-related arc systems (Karig 1971). Pearce et al. (1984) have also suggested, based on geologic observation and geochemical data, that many well-preserved ophiolite complexes formed directly above subduction zones, prior to mature arc construction.

Metal Deposits of Arc-Related Riftswas maintained during Permian time in central and western Europe, although it was clearly less significant in metallogenic terms. In the case of the Andes of South America, extensional regimes are only well documented in the extreme south, where the Rocas Verdes terrane is representative of a Cretaceous arc-related rifting event (Dalziel 1981).
