Rare earth mineral potential in SE US coastal plain

SE US coastal plain thorium values and rock types

Detailed Description

Top: National Uranium Resource Evaluation (NURE) radiometric equivalent Th (eTh; background) shows high values in parts of the Atlantic Coastal Plain inferred to contain elevated monazite and xenotime (red outlines); grayed areas represent carbonate rocks (also associated with eTh highs). Black lines delineate belts of the Piedmont and Blue Ridge Provinces. Bottom: Belts of the Piedmont and Blue Ridge colored according to rock type. Heavy mineral sands in the Atlantic Coastal Plain show regional compositional variations that suggest they were derived from specific rock types. These rock types correspond to Piedmont or Blue Ridge units adjacent to Atlantic Coastal Plain sediments. Dashed shapes delineate areas believed to contain elevated monazite and xenotime concentrations. From Shah and others, 2017, https://doi.org/10.1130/B31481.1.
