The petrography and chemistry of the Obudu type hornblende peridotite (cortlandtite), Ogoja Province, Eastern Nigeria.
Published online by Cambridge University Press: 01 May 2009
Summary
The Obudu hornblende peridotite is described and briefly compared with similar rock types from other areas. Field evidence, petrographic studies, mineralogical and chemical composition have led to the conclusion that this rock is an independent magmatic intrusion into the hypersthene tonalite (enderbite) with which it is associated, and not a member of a differentiated series.
