Replacement Veins in the Dahomeyan of Ghana

Published online by Cambridge University Press:  01 May 2009

Abstract

A basic gneiss in Ghana is traversed by light veins which are considered to have originated by replacement because gneissic mineral banding persists through them. Veins make up to 10 per cent of the rock over hundreds of square miles. It appears that a very large amount of material has been transported through the basic rocks without destroying their gneissic structure.
