Thirty-Seven Mile Creek map area, northwest of Whitehorse, straddles the contact between Coast Plutonic Complex and rocks attributed to northern Stikine Terrane. Late Triassic Little River granodiorite and Late Paleocene (57 Ma) Annie Ned granite underlie the western part of the map area. Upper Triassic to Middle Jurassic volcanic and sedimentary rocks of the Lewes River and Laberge groups underlie the eastern part of the map. The contact between Coast Plutonic Complex and Stikine Terrane is marked by the Takhini deformation zone - a region of greenschist, gneiss, mylonite, and amphibolite whose protolith is volcanic rocks of Lewes River Group. Potential mineral deposits in this map area include epithermal and mesothermal quartz veins, and magnetite skarns.
