Burial metamorphism has produced many secondary minerals in Tertiary volcanic and sedimentary rocks from western Viti Levu, Fiji. Secondary assemblages include: albite-epidote—chlorite—sphene, albite—sericite—chlorite—prehnite—pumpdlyite—quartz, mordenite(?)—quartz—celadonite, and chabazite with a phyllosilicate and any two of thomsonite, phillipsite, and analcime. The primary fabrics of the host rocks are usually unchanged.
