... that the lineaments may be related to late-stage, uranium- and thorium-rich intrusives. The Ironton lineament, a major north-south lineament, is closely related spatially to Precambrian iron and manganese deposits. Field work along the Ironton lineament suggests that it is related to a late period of Precambrian...
