The late syntectonic mylonite zone (45-100 m thick) within the dynamothermal aureole of the St. Anthony Complex in northwestern Newfoundland was derived from surrounding quartz and epidote amphibolites by deformation and the nearly isovolumetric metasomatism. Amphibolites have a composition typical of light REE-depleted ocean-floor tholeiites. Mylonites (biotite amphibolites) resemble transitional alkali basalts in major and trace element composition and in the interrelation among relatively immobile elements such as Ti, Zr, Nb, Y and P. Their REE patterns are enriched in light REE and show gradual depletion of heavy REE with La/Yb ratios ranging from 8.4 to 18.4. The results emphasize the need for caution in interpreting the concentration and ratios of any elements in mafic rocks which have been affected by metasomatism in an amphibolite facies shear zone.
