Dans le Keewatin se trouvent certainssédiments tels que la formation ferrifèreou jaspilite, des ardoises noires et desgreywackés, qui représentent probablementla série Grenville du S.-E. de lOntario. Certains dykes quon décrit avec leKeewatin sont postérieurs au Timiskaming,mais comme on ne les a jamais trouvés encontact avec la série Timiskaming, leur âgereste incertain. 6; NOTES SUR LES ROCHES KEEWATIN. Les roches Keewatin de la région de Cobalt proprementdite se divisent en quatre classes. (1) Basaltes, (2) Dia-bases et autres roches basiques, (3) Roches intrusives aci-des, (4) Sédiments.
