These ages, together with previously published fossil and isotopic data, are consistent with general westward younging of units rather than with eastward younging as has been assumed until recently by many workers, chiefly on the basis of sparse observations of bedding facings. The rocks are strongly deformed, and the possibility that tectonism rather than stratigraphic succession accounts for the age pattern cannot be dismissed. This content is PDF only.
