Includes bibliographical references. "Supracrustal rocks of western Melville Peninsula form the Prince Albert Greenstone Belt, which is comprised of rocks dated 2.9 Ga and attributed to the Prince Albert Group, a distinctive lithostratigraphic unit of the Rae Craton. The belt is subdivided into four supracrustal packages based on field relationships and lithological associations. The snake supracrustal package which is comprised mainly of mafic to intermediate metavolcanic rocks with lesser meta-ultramafic flows/sills, outcrops at the base of the succession. The Borealis supracrustal package consists of felsic to intermediate metavolcanic rocks all containing quartz phenocrysts. The Triangle Lake supracrustal package is dominated by mafic to intermediate metavolcanic rocks intercalated with banded iron-formations. The Mackar supracrustal package, which consists of metasedimentary rocks associated with felsic to mafic metavolcanic rocks, sits uncomformably over the Triangle Lake package. During mapping in the southern part of the belt, the discovery of a nickel showing in a meta-ultramafic intrusion and of a silver-zinc gossan within metavolcaniclastic rocks highlights the mineral potential of the Prince Albert Greenstone Belt in Melville Peninsula, Nunavut"--Abstract.
