Summary:Upper Carboniferous basaltic lavas from Saint John were metamorphosed under prehnite-pumpellyite conditions and some were also affected by extensive silicification. Silicification led to simple dilution of relatively immobile elements such as REE, Y, Zr, Hf, Th and Sc. The chondrite-normalized REE patterns of the silicified rocks are parallel to those of basalts. Major- and trace-element analyses of 12 West Beach volcanic rocks are presented. [P.Br.]
