摘要：

Oriented samples (107) were drilled for paleomagnetic studies from diabase sills and dykes on either side of the Boothia Uplift, Canada. Six sites at Savage Point are in sills which intrude the Aston Formation; three, at Whitehead Point, north of Point on the east coast of Prince of Wales Island, are in sills which also intrude these strata. Six sites in the Aston bay area of Somerset Island are in dykes and a sill which cut the Aston Formation; the former also intrude the Hunting Formation. No meaningful results were obtained from the Whitehead Point samples. Paleomagnetic measurements on the Savage Point samples, together with new K-Ar data, strongly suggest these sills belong to the Mackenzie igneous episode (ca. 1240 Ma).
