The paleomagnetism and UTh dating of three Canadian speleothems: evidence for the westward drift, 5.42.1ka BP

Three speleothems from western Canada have been analyzed for their paleomagnetism and U–Th activity ratios. These cave deposits do not appear to show the kind of depositional effects on the recorded magnetic signal as is often the case with sediments. In addition the signal may be referred directly to geographic coordinates so that virtual geomagnetic pole plots may be constructed. This in turn has allowed assessment of any possible bias of the …
