Abstract

Gibbsite, the dominant mineral in red and yellow earths from Mount Zomba in southern Nyasaland, is derived directly from orthoclase and acid plagioclase (albite-oligoclase). The bauxitization apparently took place at an early stage in the history of the mountain. The evidence suggests that kaolinization succeeds bauxitization in the sequence of weathering, and is related to present-day weathering conditions.
