Summary:The tectonic style of the Wabigoon granite-greenstone belt contrasts markedly with that of the Quetico slate gneiss belt, the two being separated by the Quetico fault. Isoclinally folded schistose metavolcanic rocks of the Wabigoon belt are intruded by syn-tectonic tonalitic diapirs, and there is no consistent regional tectonic trend. Metagreywackes of the Quetico belt are also isoclinically folded, but here there is a consistent E-W tectonic trend, to which the isograds are parallel. [A.C.B.]
