| Abstract | (unpublished)
The Carmacks Copper Cu-Au-Ag deposit is hosted in compositionally heterogeneous, foliated and folded, and variably migmatitic metamorphic rocks, which occur as elongate,
NNW-trending inliers in Early Jurassic granitoid rocks of the Granite Mountain batholith. Hypogene copper mineralization is restricted to metamorphic host rocks, and occurs both as foliation-parallel chalcopyrite-dominant stringers in schistose
rocks, and as net-textured bornite-chalcopyrite-dominant sulphides in the migmatitic rocks prevalent along the eastern margin of the largest metamorphic inlier. The latter style of mineralization is interpreted to originate from a sulphide melt phase
generated during partial melting of a previously mineralized protolith, during emplacement of the Granite Mountain batholith. |
