Economic mineral deposits found in oceanic terranes include: mesothermal gold-quartz veins, Cyprus-type massive sulphide, podiform chromite. platinum or cobalt associated with nickel sulphides, as well as asbestos and jade deposits. These are rither hosted by, or otherwise closely associated with oceanic crustal or mantle lithologies. Mesothermal gold-quartz veins and related placers are histor...

Abstract Bimodal volcanism occurs in a range of extensional environments that are characterized by distinctive but overlapping, lithogeochemical and isotopic signatures lithological assemblages. Where basaltic magmatism is associated with ferroan (A‐type) rhyolites, it typically the lithogeochemistry systematics rocks most beneficial constraining tectonic evolution. This study presents geochemi...

This article is designed primarily to inform clients that new 1:50 000 scale maps are currently being completed for the Findlay-Doctor Creek area (Figure IO1). A summary of preliminary results is presented for the Findlay Industrial Partnership Project after completion of three weeks of fieldwork in the Dewar and Findlay creeks map areas (82F/16, 82Wl) during 1997. The focus of the project is t...
