Dec 07, 2005 (A Wilson) - The Mishibishu Deformation Zone (MDZ) is the largerst of the deformation zones in the belt, measuring approximately 40 km in length and several hundred metres up to 1.5 km in width. The zone is located north of the Mishibishu Lake Stock and lies along the lithological contact of mafic metavolcancis to the north, with clastic metasediments to the south. The Eastern Mishibishu Deformation Zone becomes narrower approaching Lake Superior where the zone transects the external granitoids east of the greenstone belt. Deformation and alteration are less pervasive and shear zones become more dicrete than in the central MDZ. Stretchin lineations plunge to the east. The style of deformation is more brittle-ductile in the eastern MDZ. Alteration is less pervasive than, yet similar to, other zones within the belt.

Dec 07, 2005 (A Wilson) - The Glider Zone consists of recrystallize quartz and alternating sulphide and magnetite-rich iron formation. The sulphide rich layers contain stringers with massive sections of up to 30% pyrite, pyrrhotite and arsenopyrite. The zone plunges gently to the SE and is boudinaged and rotated counter clockwise into rod-shapes. The zone is terminated to the north by a NE trending diabase dike and is open to the south.
