Abstract

Columbite, beryl, lepidolite, and other economic minerals are associated with zoned pegmatites discordantly emplaced in Precambrian schists of the Alto Ligonha district, Mozambique. Mineral assemblages and textural features indicate that the pegmatites were formed by crystallization and differentiation in an essentially closed system; replacement processes may have played a part in formation of border zones and the lepidolite-albite zone adjacent to the quartz core.
