Zusammenfassung

Das Verhalten von Spurenelementen wurde in verschiedenen Metasedimenten und benachbarten mafitischen Magmagesteinen um einen Granitpluton herum untersucht. Es wird gezeigt, daß die chemischen Änderungen ihrem Gehalt und ihrer Anordnung nach in den unterschiedlichen Gesteinsgruppen verschieden sind. Der Granitisationsprozeß ist hauptsächlich von der ursprünglichen Zusammensetzung der Gesteine abhängig, welche das chemische Gefälle erzeugen. Die Mobilisation der Kationen geht vom Kontakt aus.

Abstract

The behaviour of trace elements in various metasediments and associated basic igneous rocks around a granite pluton has been studied. From these studies it has been found that the nature of chemical changes is different, both in magnitude and order, in the different groups of rocks. It is suggested that the nature of granitization has chiefly been controlled by the original composition of the rocks which has been responsible for setting up a chemical gradient across the contact under the influence of which the movement of cations has taken place.

Résumé

Nous avons étudié le comportement des éléments différents dans les métasédiments différents et dans les roches pyrogènes et basiques associeés autor d'un pluton granite. Nos études montrent que la nature des changements chimiques diffère en magnitude et en ordre dans les groupes différents des roches. On a suggéré que la nature de granitisation est principalement controlée par la composition originale des roches qui a produit un gradient chimique le long du contact. Le mouvement des cations a été influencé par ce contact.
