Structural Analysis of the Amisk and Missi Rocks North of Amisk Lake, Saskatchewan
Volcanic, sedimentary and intrusive rocks of Precambrian age in the southwestern part of the Churchill Province of the Canadian Shield just west of Flin Flon, Manitoba have a complex structural pattern as the result of three superposed phases of deformation. All rocks have.undergone lower greenschis...
