PALEOMAGNETISM OF PRECAMBRIAN ROCKS NEAR COBALT, ONTARIO
A paleomagnetic study was made on 32 hand samples from Precambrian rock units in the Silverfeilds Mine, Cobalt, Ontario. The samples from the Keewatin lavas proved unsuitable for paleomagnetic study. The Cobalt Group sediments and Nipissing diabase sill have stable primary remanences, which yield po...
