Abstract Albite porphyroblasts are widely distributed in pelitic and semi‐pelitic schists of the Fleur de Lys Supergroup, western Newfoundland. Textures and mineral assemblages indicate that albite grew during nearly isothermal decompression from P‐T conditions of about 500° C, 9 kbar, to conditions...
