Normative plot showing normalized rare-earth-element (REE) concentrations from 44 mafic rock samples plotted against midocean ridge basalt (MORB) standard of Taylor and McLennan (1985). For a more detailed explanation, contact Jonathan Tso at jtso@radford.edu.
 
Figure 9. Normative plot showing normalized rare-earth-element (REE) concentrations from 44 mafic rock samples plotted against midocean ridge basalt (MORB) standard of Taylor and McLennan (1985). Lighter trace elements are enriched; heavier trace elements are depleted relative to the standard. Refer to McDowell (2001) for sample locations and analytical results.
