StructureThe Golden Horn Batholith Was Intruded Into The Hozameen Fault, The Major Fault Bounding The Southwestern Side Of The Methow Basin. Radiometric Dating Suggests That Magmatic Crystallization Occured At Approximately 47 M.Y. K-Ar Biotite, Fission-Track Allanite, Rb-Sr Isochron Ages That Fall Between 38 And 42 M.Y. Probably Represent The Age Of Postcrystallization Hydrothermal Alteration (Stoffel And Mcgroder, 1990).
