Malawi Glimmerites
Abstract
A swarm of glimmerites lie within amphibolite facies gneisses in the Shire valley of southern Malawi. Their field relations, distribution, mineralogy and geochemistry suggest that they are metasomatized ultramafic intrusives, but the possiblity that they may be related to alkaline ultramafic magmatism is discussed.
