The ellipsoidal greenstone flows are only of Keewatin age. The Knife Lake series consists of about 10–20 recognizable members. The terms “Ogishke conglomerate” and “Agawa formation,” as used formerly, should be discarded.Conglomerates appear at many horizons in the series. The Knife Lake series consists of continental sediments and contains no major unconformity. There was considerable volcanic activity during the time of sedimentation. Many longitudinal faults divide the area into distinct structural segments. The development of synclinoria resting on the Archean basement complex is discussed, and it is thought that the distance of the folds above this basement can be inferred from the arrangement of the folds.
