Popis:	The Radiore Cu-Zn massive sulfide deposit occurs in Archean metavolcanic rocks of the Abitibi greenstone belt in northwestern Quebec. The ore forms a stratiform lens between a massive rhyolite flow and a unit of mixed basaltic and intermediate flows. Intrusions of thick dykes of gabbro-diorite, quartz-diorite and granodiorite, and of the Bell River igneous complex, closely surround the ore lens. All the volcanic rocks, the quartz-diorite, grandiorite and the igneous complex are tholeiitic, whereas the gabbro-diorite is of calc-alkaline affinity. Sedimentary structures are prevalent in the ore, and heavily chloritized and biotitized rocks form a stratiform alteration zone mainly below the ore, indicating a distal-type deposit.
